Materials based on epoxy-diane resin modified with glycolyzed products were obtained. It was found that the use of the developed oligomers with optimal content of epoxy-diane resin as modifier leads to an increase in some characteristics of the resulting materials: elasticity, tensile strength and elastic modulus at static bending, viability of the composition. The use of glycolysis products is advisable because it is a promising method for recycling of household waste polyethylene terephthalate. It is characterized by ease of synthesis, as well as low cost and availability of initial components, and makes it possible to increase the physical and mechanical properties of structural materials based on epoxy resins, as well as contribute to solving environmental problems.","PeriodicalId":20254,"journal":{"name":"Plasticheskie massy","volume":"15 18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141814776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A good agreement was found between the calculated and experimental data on the increase in permeability with increasing pressure.
