The parameters of the diffusion of ions and the kinetics of the formation of carbonyl compounds at the interface with the copper layer are determined over a wide temperature range. In the region of small film thicknesses the diffusion of copper ions is associated with the distribution of the PE oxidation front and with participation of the copper ions in the oxidation reactions. In thick films the diffusion of copper ions is two-stage in nature, because of the delay in autocatalytic oxidation of the external layer compared with oxidation of the PE layer/metal interface catalysed by copper compounds.</p></div>","PeriodicalId":20280,"journal":{"name":"Polymer Science U.s.s.r.","volume":"33 8","pages":"Pages 1608-1615"},"PeriodicalIF":0.0,"publicationDate":"1991-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0032-3950(91)90047-T","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81056648","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}
