I t is shown that the value of the activation energy is 123 kJ/mol, and the thermal effect of the reaction is 86 kJ/mol. It has been proved that the interaction of the studied catalytic complex with p -methylstyrene in toluene of stoichiometric composition 1:1:2 is a coordinated process.","PeriodicalId":495513,"journal":{"name":"Plastičeskie massy","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134944736","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}

It has been found that the identified low-molecular impurities are of raw material origin and do not significantly affect the thermal stability and rheological behavior of the studied carbon-filled compositions during processing by extrusion and injection molding. The thermal characteristics of carbon-filled compositions are significantly influenced by the chemical nature of the introduced technological and modifying additives.","PeriodicalId":495513,"journal":{"name":"Plastičeskie massy","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135546646","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}
