POLYPROPYLENE RESIN COMPOSITION FOR EXTRUSION MOLDING AND EXTRUSION FILM AND SHEET USING THE SAME

摘要

PURPOSE: To obtain a polypropylene resin composition capable of providing a film and a sheet having good moldability and processability, transparency, flexibility and touch feeling and hardly having fish eye by adding a diamine- monocarboxylic acid polycondensation product or a diamine-monocarboxylic acid-polybasic acid polycondensation product to a crystalline polypropylene. CONSTITUTION: This polypropylene resin composition for extrusion molding is obtained by blending 100 pts.wt. crystalline polypropylene with 0.005-10 pts.wt. diamine-monocarboxylic acid polycondensation product or diamine- monocarboxylic acid-polybasic polycondensation product. The resin composition is subjected to extrusion molding to provide the objective extrusion film and sheet having good touch feeling and <=55kg/mm<2> Young's modulus.
