New epoxy mortars suitable for construction repair made from epoxy oligomer, amine and modified PET waste hardeners mixed with sand were prepared. Three types of carboxyl terminated PET (CTPET) were used as co-hardeners, along with an amine, to prepare new combination linkage epoxy mortars. Investigation of the viscoelastic properties revealed that the CTPETs influenced the storage modulus at glassy state and the rubbery plateau, indicative of interfacial adhesion between the epoxy matrix and sand aggregates. Additionally, the damping behavior and glassy temperature were increased with the addition of CTPET. Moreover, the combination linkage of ester groups from the CTPET likely contribute to the enhancement of compressive strength and flexural strength in the epoxy mortar. The results of absorption and flexural change after immersion in solution, as well as the interfacial flexural bonding strength with ordinary cement-based material were also investigated.","PeriodicalId":738,"journal":{"name":"Polymer Science, Series A","volume":"65 5","pages":"568 - 579"},"PeriodicalIF":1.0,"publicationDate":"2023-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138516503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some potential applications are recycling PBT and PA6 into insulation or fire-retardant materials by mixing with an appropriate amount of fiberglass (GF). PBT/PA6/GF mixtures are prepared by injection molding method with 0, 3, and 6% GF in each PBT/PA6 mixture in 25/75, 50/50, and 75/25 respectively. After the injection molding, the samples are tested for tensile strength according to ASTM D638. The average tensile strength of PBT/PA6 at 25/75, 50/50, 75/25, and 100% PBT is 48.58, 42.52, 34.91, and 52.21 MPa. It shows that the tensile strength of the PBT/PA6 mixture decreases as the PBT content increases. The average elongation of the samples had a considerable deviation, with 25%PBT/75%PA6 reaching the maximum value of 37.92% and the 75%PBT/25%PA6 sample getting a nominal value of 0.94%. Besides, when mixing GF fiberglass into a PBT/PA6 blend with a 0 and 3% GF ratio, the tensile strength changes and decreases instability. But at 6% GF, there is a clear improvement as tensile strength gradually increases at all PBT/PA6 ratios. Therefore, to obtain an excellent tensile strength value, the GF content in the mixture should be more significant than 6% by weight of the blend. The elongation of PBT/PA6/GF samples is stable when the highest deviation is slight between the ratios. This research aims to serve as a reference for developing a method of mixing materials to produce the desired mechanical properties.","PeriodicalId":738,"journal":{"name":"Polymer Science, Series A","volume":"65 5","pages":"543 - 549"},"PeriodicalIF":1.0,"publicationDate":"2023-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136133986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study of the elastic and strength behavior and dynamic mechanical properties of the vulcanizates demonstrates that the sulfur-peroxide vulcanization system provides the best parameters, in particular at low temperatures. An examination of elastic and hysteresis properties of the samples before and after vulcanization, which are measured under dynamic loading in a wide frequency and strain range, allows one to describe the features of physicochemical interactions in polymer-elastomer materials depending on the used vulcanization system.

Three deformation modes have been probed. In the first case, a disc-shaped polymer specimen has been put between two 5 mm thick discs of the lead–tin alloy and squeezed in the press. In the second and the third cases, planar elongation has been performed in the so called “dead channel”, i.e., the channel with fixed side walls, the film being elongated due to decrease in the width or thickness, respectively. The plots of true yield stress at different draw ratios have formed a common master curve. At high total draw ratio Λ, the true yield stresses have been close for the considered three types of drawing in the metal. At the draw ratio Λ > 2.6, the neck has not appeared, and the specimen has been deformed uniformly. When the film in the channel is elongated due to the decrease in thickness at constant width, the specimen width has been mainly decreased during subsequent elongation in the testing machine. When the film in the channel is elongated due to the decrease in width at constant thickness, further elongation has mainly led to the decrease in the specimen thickness. The true stress Σ has been expressed as Σ = Σ0 + KΛ3, with K being a constant. Deformation of the polymer in the channel occurred with the formation of shear bands. At the preliminary draw ratio Λ = 1.82, the bands have been oriented at the angle 21.5° with respect to the stretching axis. The planar elongation has led to abnormally strong deformation softening of the polymer. The drawing has been accompanied by an increase in the elasticity modulus of the polymer. The obtained results have suggested that the macromolecules orientation is the main reason for strain hardening of the polymer.","PeriodicalId":738,"journal":{"name":"Polymer Science, Series A","volume":"65 4","pages":"337 - 346"},"PeriodicalIF":1.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134797932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of thermal oxidation on thermophysical characteristics (the heat of melting and the melting temperature) measured by DSC and changes occurring in the polymer investigated by IR spectroscopy is studied. Changes in the structure of PP during thermo-oxidative degradation are studied by DSC at 140 and 170°С, that is, before and after melting of the samples. It is shown that the oxidized PP in the composites possesses a higher degree of crystallinity and a more perfect structure than the pure PP. At 170°С the effect of thermo-oxidative stabilization is observed only at low filling degrees (up to 3 wt %), in agreement with the TGA data. An analysis of IR spectra demonstrates that the presence of nanotubes in PP‑based composites during oxidation slows down the formation of oxygen-containing groups in the polymer.
