THERMOPLASTIC POLYMER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a thermoplastic polymer composition which comprises a mixture of a modified olefin polymer having a specific chemical structure and a polar thermoplastic polymer and shows excellent mechanical characteristics and oil resistance in a variety of applications for resin molded products and elastomers. SOLUTION: This composition is produced by admixing (B) 99-1 pts.wt. of a modified olefin polymer to which at least one selected from the group consisting of ethylenically unsaturated group-containing carboxylic acids (derivatives) is bonded in an amount of 0.05-20 pts.wt. per 100 pts.wt. of a component A and (C) 1-99 pts.wt. of a polar thermoplastic polymer to (A) a main olefin polymer which comprises ethylene and at least one ofα-olefins of 3-12C, preferably 6-12C, has a density of 0.858-0.885g/cm<3> and <=3.0Mw/Mn where Mw is a weight-average molecular weight and Mn is a number-average molecular weight calculated from a gel permeation chromatography.
