The resulting polymers were analyzed using IR spectrometry, gel permeation chromatography, differential scanning calorimetry, thermogravimetric analysis and melt flow index measurements. Quantitative characteristics of the heat-resistance and processability indicators of synthesized PEIs depending on the content of rigid-chain fragments have been determined. Results show that increasing the content of BPDA and PMDA units in the PEI structure enhances the heat resistance and thermal stability of the polymers, although the melt flow index decreases. The explanation of the observed effect based on the growth of intermolecular interaction and the formation of a crystalline phase is given. Optimal ratios of precursor dianhydrides were identified to achieve the best balance of heat resistance and processability. The resulting PEIs of optimal structure have glass transition and thermal destruction temperatures up to 25–40°C higher in comparison with unmodified PEI whilst retaining the ability to be processed through the melt. The obtained results open up broad application prospects of the developed co-PEIs as highly heat-resistant engineering thermoplastic materials.","PeriodicalId":739,"journal":{"name":"Polymer Science, Series B","volume":"67 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145169453","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}

Larvae were cultured with foamed polystyrene in the absence of food and in control groups with normal nutrition. Most larvae survived and successfully developed into pupae. The effect of larvae on polystyrene is manifested by its mechanical destruction when larvae build tunnels in the volume of polystyrene material, resulting in the formation of a finely dispersed fraction of polystyrene (i.e., microplastics). FTIR, Raman, and NMR spectrometry methods revealed no significant differences in the original polystyrene and polystyrene crushed by larvae; also, according to the GPC data, no significant change in the molecular weight of polystyrene was detected as a result of contact with Z. morio larvae and passage through their gastrointestinal tract. The data obtained confirm that the main result of larvae impact on polystyrene foam is its crushing with formation of microplastic without chemical modification and change of molecular weight.","PeriodicalId":739,"journal":{"name":"Polymer Science, Series B","volume":"67 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145169454","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 modeling results are compared with the experimental data obtained for carbon black-filled compositions based on NBRS-40AMN rubber, including the vulcanizing agent 1,4-di(tert-butylperoxyisopropyl)benzene in different dosages. The mathematical model of the vulcanization kinetics of the compositions relies on the analysis of the formal kinetic scheme of radical reactions occurring during peroxide vulcanization in the presence of air oxygen. Using this model the influence of oxygen on the ratio of carbon–carbon and ether–ether crosslinks in the formed vulcanization network is analyzed. To describe the deformation curves of peroxide vulcanizates with different content of the vulcanizing agent, a model based on the series decomposition of the network strain energy by invariants of the left Cauchy–Green strain tensor and including the linear viscoelasticity equation is proposed. The vulcanizate breakdown process is characterized by a kinetic equation in which a network deformation model is used which allows an adequate description of the deformation curves of crosslinked elastomers up to failure. By analyzing the dependences of the model parameters on the content of the vulcanizing agent, conclusions are made about changes in the structure of the vulcanization network with increasing degree of crosslinking.","PeriodicalId":739,"journal":{"name":"Polymer Science, Series B","volume":"66 6","pages":"798 - 807"},"PeriodicalIF":1.0,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145168670","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 effects of the temperature, the compound initiator ratio, the compound emulsifier ratio, the ligand type and the content on the polymerization dynamics were examined, and the polymer was characterized by infrared spectroscopy and 1H NMR. This study revealed that the monomer conversion rate and the apparent polymerization rate are positively correlated with the reaction temperature, and the apparent activation energy of the reaction was Ea = 57.63 KJ/mol. When benzyl bromide was used as the initiator alone, the initiation efficiency of the system was low. After EBIB was added, the initiation effect was greater for benzyl bromide : EBIB = 7 : 3, and the conversion rate and polymerization rate were positively correlated with the amount of reducing agent. The monomer conversion rate and apparent growth rate constant were the greatest when the mass ratio of the emulsifier sodium dodecyl sulfate and sodium dodecyl benzene sulfonate was 7 : 3. Different ligands affected the monomer conversion rate and apparent growth rate constant, and with increasing ligand content, the monomer conversion rate and apparent polymerization rate constant increased.
