PROPYLENE POLYMER COMPOSITION

摘要

PURPOSE:To provide a propylene polymer composition produced by compounding a crystalline propylene polymer with powder composed of a non-meltable silicone resin having three-dimensional network structure and specific particle diameter and sphericity and giving a film having high transparency, antiblocking property, slipperiness and openability. CONSTITUTION:This propylene polymer composition is produced by compounding 100 pts.wt. of a crystalline propylene polymer with 0.01-1 pt.wt. of powder having an average particle diameter of 0.5-7mum and a sphericity (f) defined by the formula of >=0.8 [A is cross-sectional area of the powder (mm<2>); Dmax is the maximum diameter (mm) of the cross section] and composed of a non- meltable silicone resin having three-dimensional network structure.
