聚丙烯树脂组合物及其制造方法、双轴拉伸膜及其制造方法、以及薄膜电容器用电容器膜
Abstract:
本发明提供一种挤出特性良好、成膜时外观良好、并且厚度的不均匀少、力学特性的平衡优异、显示高的耐热性的聚丙烯树脂组合物。该聚丙烯树脂组合物满足以下的条件(1)～(3)。(1)基于ASTM D1238、以230℃、2.16kg负荷测得的熔体流动速率(MFR)为1～10g/10分钟。(2)使用13C－NMR测得的全同立构五单元组分率为0.930以上。(3)Mz为60万～140万，Mw/Mn为6.5～14.0。
Abstract(English):

Provided is a polypropylene resin composition having superior balance in mechanical properties, good extrusion properties, a good appearance and low variation in thickness when made into a film, and exhibiting high thermal resistance. Said polypropylene resin composition satisfies the following requirements (1)-(3). (1) The melt flow rate (MFR), as measured at 230 DEG C and a load of 2.16 kg in conformance to ASTM D1238, is 1-10 g/10min. (2) The isotactic pentad fraction measured using 13C-NMR is at least 0.93. (3) Mz is 600,000-1,400,000 and Mw/Mn is 6.5-14.0.
