Abstract

PURPOSE: To prepare a rubber-moldified styrene resin composition which can be vacuum formed into an article having uniform section, by compounding a resin obtained by mixing, melting and polymerizing a monovinyl aromatic compound and a rubber, with a liquid rubber and an internal lubricant.
CONSTITUTION: The objective rubber-modified styrene resin composition for vacuum forming, is prepared by compounding (A) 100 parts by weight of a resin obtained by mixing, melting and polymerizing (a) 90W98 parts of a monovinyl aromatic compound such as styrene and (b) 2W10 parts of a rubber (pref. polybutadiene), with (B) 0.2W5 parts of a liquid rubber which is flowable at ≤100°C, e.g. polybutadiene, styrene-butadiene copolymer, etc., pref. having a number average molecular weight of ≤5000, and (C) 0.5W3 parts of an internal lubricant such as a mineral oil, butyl stearate, etc., which are conventional polystyrene additives.
