丙烯系聚合物、丙烯系聚合物组合物及其用途

Propylene polymer, a propylene polymer composition, and use of those

Abstract

The invention relates to a propylene polymer, a propylene polymer composition, and use of those. The propylene polymer is characterized by including more than 9mol% of constitution units derived from propylene (wherein, the total quantity of the constitution units in a polymer (A) is 100mol%), and meeting conditions [1] and [2-2], [1]: a syndiotactic five-unit component ratio (rrrr fraction) measured by 13C-NMR is more than 85%; [2-2]: a melting point (Tm) calculated by a differential scanning catorimetry (DSC) is more than 150 DEG C and the melting heat (Delta H) is more than 50mJ/mg.
本发明涉及一种丙烯系聚合物、丙烯系聚合物组合物及其用途,该丙烯系聚合物的特征在于,含有超过90mol%的源自丙烯的构成单元(其中,以该聚合物(A)中的构成单元的总量为100mol%),并满足下述条件[1]和[2-2],[1]:采用13C-NMR测定的间规立构五单元组分率(rrrr分率)在85%以上;[2-2]:使用差示扫描量热计(DSC)求得的熔点(Tm)在150℃以上,且熔化热(ΔH)为50mJ/mg以上。
