The adhesion build-up mechanism involves the chemical reaction of the rubber skim compound and copper of the brass coating, forming CuxS, ZnS and ZnO layers at the rubber-brass interface. All factors which affect the reactivity of a brass surface for CuxS formation, have an effect on the adhesion but excessive CuxS leads to the loss of adhesion. The adhesion force tends to maximum value with optimum copper content in the plating but better retention of after aging achieves at a lower copper content. A higher sulfur content is necessary than for ordinary rubber. There is an optimum amount of organic acid cobalt salt, as adhesion diminishes when the rubber is formulated with large amounts. A high level of unaged adhesion can be obtained if products with a combination of low cobalt and high sulfur content are formed on the brass surface.","PeriodicalId":405949,"journal":{"name":"Journal of the Society of Rubber Industry,Japan","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114405901","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}

The topics and their principal achievements are as follows. The polymer components used are polyiosprene(I), polystyrene(S), poly(2-vinylpyridine)(P) and poly(4-hydroxystyrene)(H), and almost all the polymer samples were prepared by anionic polymerizations and therefore have narrow molecular and composition distribution. 1) Complex structures from multiblock terpolymer: Undecablock terpolymers of the PISISISISIP type and hexablock terpolymers of the PISISI type with both have much different block chain lengths show hierarchical structures with double periodicity. 2) Periodic and aperiodic tiling structures from star-shaped terpolymers: Bulk structures of IXSYPZ star-shaped terpolymers were observed and simply periodic Archimedean tiling structures and quasicrystalline tiling structures with dodecagonal symmetry have been found. 3) New self-assembly manner of block copolymer/homopolymer blend: A polystyrene-b-poly(2-vinylpyridine)(SP) diblock copolymer and H homopolymer can be mixed together to form periodic two-phase structures because of hydrogene bonding interaction between P and H components. 4) Supramacromolecular self-assembly by ionic bonding interaction: Polystyrene with 13 styrene sulfonic acid units on one chain end and polyisoprene with amino group on one chain end tend to form periodic two-phase structures due to acid/base ionic bonding depending on compositions.","PeriodicalId":405949,"journal":{"name":"Journal of the Society of Rubber Industry,Japan","volume":"2015 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114455193","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}
