[0116]The components shown in Table 1 and 0.3 parts by weight of a hydroxyphenyl antioxidant were mixed in a Hansel mixer for 3 to 10 minutes to prepare a mixture. The mixture is fed into a conventional twin-screw extruder at a rate of 30-60 kg / h, and heated at 180-280° C.

[0117] screw speed in rpm to extrude into pellets. Melt strength was measured after the resin pellets were dried at 100°C for 3 hours. Subsequently, the resin pellets were molded into test samples using a 6-oz injection molding machine at 180-280°C with a barrel temperature of 40-80°C. The physical properties and chemical resistance of the test samples were measured after placing the samples at 23°C and 50% relative humidity for 40 hours.

Abstract

The present invention provides a chemical and impact resistant thermoplastic resin composition having improved extrudability. In one embodiment, the thermoplastic resin composition comprises (A) about 1 to about 98 % by weight of an epoxy group-containing vinyl copolymer resin; (B) about 1 to about 98 % by weight of a rubber modified styrene copolymer resin; (C) about 1 to about 98 % by weight of a polyester resin; and about 1 to about 6 parts by weight of an aromatic vinyl-vinyl cyanide copolymer resin having a weight average molecular weight of about 1,000,000 to about 5,000,000, per 100 parts by weight of a base resin comprising (A)+(B)+(C). In another embodiment, the thermoplastic resin composition comprises (A) about 1 to about 98 % by weight of an epoxy group-containing vinyl copolymer resin; (B) about 1 to about 98 % by weight of a rubber modified styrene copolymer resin; (C) about 1 to about 98 % by weight of a polyester resin; and (E) about QOl to about 1 part by weight of an epoxy-based additive, per 100 parts by weight of a base resin comprising (A)+(B)+(C).

Description

technical field [0001] The present invention relates to a chemical-resistant and impact-resistant thermoplastic resin composition having improved extrudability. More specifically, the present invention relates to thermoplastic resin compositions having improved extrudability and excellent chemical resistance and impact resistance, wherein epoxy group-containing vinyl copolymer resins, rubber-modified styrene Copolymer resins and polyester resin base resins are added with ultra-high molecular weight aromatic vinyl-acrylonitrile copolymer resins (vinyl-vinyl cyanide copolymer resins) and / or epoxy-based (epoxy-based) additives . Background technique [0002] Acrylonitrile-butadiene-styrene copolymer resin (hereinafter referred to as 'ABS resin') is a resin in which a copolymer of styrene monomer and acrylonitrile monomer grafted to a butadiene rubber polymer (hereinafter referred to as 'g-ABS') is dispersed in a matrix of styrene-acrylonitrile copolymer resin (hereinafter ref...
