OLEFIN POLYMER AND USE THEREOF |
摘要 |
Disclosed is a novel olefin polymer exhibiting excellent heat resistance while having an excellent balance among various physical properties. Such an olefin polymer contains 50-100 weight% of a constitutional unit derived from 4-methyl-1-pentene and 0-50 weight% of another constitutional unit derived from at least one olefin selected from olefins other than 4-methyl-1-pentene which have 2-20 carbon atoms. The olefin polymer is characterized in that (i) the isotactic diad tacticity is not less than 70%; (ii) the ratio (Mw/Mn) between the weight average molecular weight (Mw) and the number average molecular weight (Mn) determined by gel permeation chromatography (GPC) is 1.0-3.5; and (iii) the limiting viscosity [eta] is not less than 0.5 (dl/g). ® KIPO & WIPO 2007
