THERMOPLASTIC RESIN COMPOSITION EXCELLENT IN PROCESSABILITY

摘要

PROBLEM TO BE SOLVED: To obtain a thermoplastic resin composition excellent in mechanical strength and surface appearance and capable of stabilizing the quality due to the productivity improved by excellent processability. SOLUTION: This thermoplastic resin composition is a partially or a completely cross-linked thermoplastic resin composition comprising (A) 1-99 pts.wt. of a cross-linkable thermoplastic elastomer produced by using a metallocene-based catalyst and (B) 1-99 pts.wt. of a thermoplastic resin [the total amount of the components (A) and (B) is 100 pts.wt.]. The composition has 2.0-5.0 molecular weight distribution (Mw/Mn) which is the ratio of the weight-average molecular weight (Mw) to the number-average molecular weight (Mn) calculated by a gel permeation chromatography(GPC) of the component (A) and at least two peaks by the measurement of the molecular weight distribution according to the GPC.
