However, recently, Yao had clearly shown that side chain crystalline block copolymer ( SCCBC ) has an ability to modify the PE surface property chemically. In this study, by using the SCCBC, we had tried to stain the very high molecular weight PE fi ber that is known to be the most dif fi cult product with respect to modifying the surface property, not only chemically but also physically. From the results, the high molecular weight PE fi ber can be dyed by using the SCCBC and it had shown very high durability. This study shows that the application area of SCCBC is very wide and useful.","PeriodicalId":17878,"journal":{"name":"Kobunshi Ronbunshu","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79892629","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}

Sakaguchi","doi":"10.1295/KORON.2018-0042","DOIUrl":"https://doi.org/10.1295/KORON.2018-0042","url":null,"abstract":". To develop an epoxy resin having a high glass transition temperature and heat resistance, copolymerization of an epoxy group - containing vinyl ether and a maleimide derivative was carried out. Radical copolymerization of 2 - vinyloxyethylglycidyl ether ( VEGE ) and N - phenylmaleimide ( NPMI ) with AIBN were carried out in benzene or THF to give polymers having a molecular weight of 120,000 to 250,000 ( in case of benzene ) and a molecular weight of about 6,000 ( in case of THF ) in high yield, respectively. On the other hand, the copolymerization in the absence of AIBN hardly progressed in benzene, but in THF the polymers with a molecular weight of about 5,000 were obtained in high yield. 1 H NMR spectroscopy showed that the structure of the products is a copolymer composed of VEGE units and NPMI units. MALDI - TOF - MS spectroscopy revealed that the VEGE units and NPMI units are arranged mainly in an alternative manner. The glass transition temperature ( T g ) of the copolymers greatly varied depending on the copolymer composition and remarkably increased as the content of NPMI units increased. The thermal decomposition temperature ( T d ) of the copolymers was about 300 ° C or higher depending on the content NPMI units. By curing the reactive epoxy groups in the copolymers with multifunctional aromatic amines, novel heat - resistant epoxy cured resins with high T g were obtained.","PeriodicalId":17878,"journal":{"name":"Kobunshi Ronbunshu","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82925404","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}

ASAXS revealed that the size of the hydrophobic core and the aggregation number of PMAA - b - PBrEMA micelles drastically decreased with an increase in the pH from 4.8 to 12.5. It was concluded that the drastic reduction of the size of PMAA - b - PBrEMA micelles in alkaline conditions was caused by the reduced electrostatic repulsion between anionic PAA chains in the corona layer of the micelles.","PeriodicalId":17878,"journal":{"name":"Kobunshi Ronbunshu","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75874213","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}
