It was established that up to 97% of isoprene units in macromolecules predominantly occur in 1,4-trans configuration. The content of 3,4-units is twice that of 1,2-units and does not exceed 4%. It was shown that macromolecules contain homosequences of comonomer units. 3,4-Units of isoprene are surrounded predominantly by trans-units. Based on the data of 1H NMR spectroscopy and copolymerization reactivity ratios, a conclusion is made about the configuration of macromolecules as a whole.

Structural investigations by FTIR and UV–Vis spectroscopy confirmed successful doping and chemical interactions between the polymers and MoO3. X-ray diffraction (XRD) analysis verified the preservation of the orthorhombic α-MoO3 crystalline phase across all composites, with peak broadening indicative of polymer-induced lattice strain and reduced crystallite size due to acid treatment and polymer embedding. Morphological examination using scanning electron microscopy (SEM) revealed exfoliated MoO3 nanobelts uniformly dispersed within hierarchically porous polymer matrices, promoting increased surface area and ion accessibility. Thermal analyses via thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) demonstrated enhanced thermal stability and distinct degradation behaviors relative to pristine polymers, attributed to robust polymer–inorganic interfacial interactions that enhance composite stability. These findings suggest that the hybrid nanocomposites, combining enhanced thermal robustness and tunable morphology, are promising for energy storage devices, electrochemical sensors, and thermally stable conductive coatings.","PeriodicalId":739,"journal":{"name":"Polymer Science, Series B","volume":"67 4","pages":""},"PeriodicalIF":1.0,"publicationDate":"2026-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147571107","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}

Over time, environmental elements such as heat, light, and atmospheric oxygen can destroy or damage the polymer material, and in this regard, polymer stabilizers play a protective role. Polymer stabilizers must be durable and withstand certain climatic conditions well throughout their service life. With the correct application of these stabilizers, the overall performance, durability, and safety are significantly improved, as the applied stabilizers guarantee the resilience and durability of the polymer material, preventing the deterioration of its physical and mechanical properties caused by external influences. In recent years, sterically hindered phenols and their functionally substituted derivatives, which can act as antioxidants, heat stabilizers, and other types of stabilizing compounds, have been increasingly used as such stabilizers. This paper analyzes the results of research in the field of developing new effective stabilizers for a number of polymer materials, such as polyvinyl chloride, polyethylene, and polypropylene. The main advantages and disadvantages of the described stabilizers are shown, and the results of the authors' own research in the field of obtaining new effective stabilizers are presented.","PeriodicalId":739,"journal":{"name":"Polymer Science, Series B","volume":"67 3","pages":""},"PeriodicalIF":1.0,"publicationDate":"2026-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147340053","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}

UV–visible spectroscopy revealed a red-shift in absorption, with an optical band gap of 2.69 eV, indicating semiconductive behavior. Structural analysis using XRD showed semicrystalline characteristics, while TGA demonstrated good thermal stability with decomposition onset at 455°C. SEM images revealed a rough, globular surface morphology with porous features. Oligomer yield was optimized by varying reaction parameters, with a maximum yield of 95.1% achieved at room temperature using 5% Maghnite-H+ as a catalyst over 24 hours.
