The theological and crystallization behaviors of pp / eoc blends showed that increasing octene content in eoc elastomer resulted in a decrease of eoc fluidity , an increase of the adhesive fracture energy with pp ( that is compatibility with pp ) and of hindering pp crystallization 研究了pp eoc体系流变和结晶行为,发现随辛烯含量的增加, eoc流动性变差,与pp的界面粘结能增大,即相容性提高,对pp结晶的阻碍作用增强。
Ethylene / octene copolymer sythesized by metallocene catalyst was a new kind of thermoplastic elastomer , which was molded as elastomer material by plastic common molding process such as injection , extrusion and blowing and also by rubber process such as chemical crosslinking by peroxide 采用茂金属催化剂合成的乙烯辛烯共聚物是一种新型热塑性弹性体,可用注射、挤出、吹塑等常用加工方法成型,又可用过氧化物进行化学交联,用橡胶加工方法制成弹性体材料。
Preparation of polymer composites is one of the important methods to realize high performance of polymer materials . in this paper , a newly developed ethylene - octene copolymer ( eoc ) , catalyzed by metallocene catalysts , was used as an impact modifier for pp instead of traditional modifier ( epdm ) . the relationship between the structure and properties of polypropylene composites toughened and reinforced by eoc and cacos respectively or together was studied systematically 聚合物复合材料的制备是实现高性能聚合物材料的重要途径之一,本论文采用茂金属催化剂合成的新型聚烯烃弹性体乙烯-辛烯共聚物( eoc )代替传统的三元乙丙橡胶,对eoc和caco _ 3两种增韧剂分别和协同增韧增强聚丙烯复合材料体系的形态结构与性能的关系进行了系统的研究,围绕高性能、应用探索和理论研究三个方面作了较为深入的探索和分析,获取了很多有价值的信息,为高性能聚丙烯复合材料的开发和应用作了理论铺垫,主要结果如下: 1
Octene is an alkene with the formula . Several isomers of octene are known, depending on the position of the double bond and the branching of the carbon chain.
