摘要
介绍了日本三菱油化公司 (现为三菱化学公司 )BC - 8嵌段聚丙烯的开发经过及实际结构。近年结构分析结果发现BC - 8嵌段聚丙烯并非嵌段物 ,而是由均聚聚丙烯、EPR(乙丙橡胶 )以及聚乙烯 (链上有少量丙烯单元但并非嵌段物 )三者组成的高分子合金。
The development circumstances of BC-8 block polypropylene by Mitsubisi Chemical Co.( Formly Mitsubisi Petrochemical Co.) and its actual structure are introduced.It is shown by recent published literature that the so-called BC-8 block PP is not a block copolymer indeed but a polymer alloy which consists of homopolypropylene,EPR and polyethylene with a few propylene segments.
