Title:

AROMATIC VINYL POLYMER RESIN COMPOSITION, RESIN FOAMING SHEET, PRODUCTION OF RESIN FOAMING SHEET AND VESSEL

Document Type and Number:

Japanese Patent JP2000212357

Kind Code:

A

Abstract:

To obtain an aromatic vinyl polymer resin composition excellent in heat resistance and oil resistance and excellent in balance of tensile elongation, impact strength and stiffness and suitably used as a material for food vessels, etc., corresponding to cooling by microwave oven.

This aromatic vinyl polymer resin composition features comprising (A) 30-95 pts.wt. aromatic vinyl polymer resin and (B) 70-5 pts.wt. propylene- ethylene copolymer containing 13-20 wt.% amorphous part obtained by fractionation by crystallization and having 20-40 wt.% ethylene content in the amorphous part and (C) 1-15 pts.wt. hydrogenated product of styrene-diene block containing 50-90 wt.% styrene based on 100 pts.wt. total amount of the components A and B. This vessel is obtained by molding the resin composition.
