preparation example Construction

[0024] The polymerization method of styrene-acrylonitrile copolymer can adopt block polymerization method, solution polymerization method, suspension polymerization method, emulsification polymerization method, etc., among which block polymerization method or solution polymerization method is preferred. In addition, the method for preparing the styrene-acrylonitrile copolymer preferably includes performing polymerization using a reactor capable of continuous block or solution polymerization. The reactor includes: a columnar flow reactor, a completely mixed reactor (CSTR), or a tube reactor with static mixing elements, among which the completely mixed reactor is preferred. The number of reactors used may be one, or two or more reactors may be used in combination.

[0025] In one embodiment, the preparation method of the styrene-acrylonitrile copolymer is carried out by solution polymerization. The solvent used in the solution polymerization reaction is, for example, toluene, e...

Abstract

A thermoplastic resin composition and a molding product thereof are disclosed. The composition includes 60-90 wt% of polycarbonate, 5-30 wt% of a styrene-vinyl cyanide based copolymer, 1-15 wt% of a vinyl cyanide-diene-styrene based copolymer and 0.5-15 wt% of an acrylate-diene-styrene copolymer. The acrylate-diene-styrene copolymer has a diene based monomer unit the weight of which is 71-90% of the weight of the acrylate-diene-styrene copolymer.

Description

technical field [0001] The present invention relates to a polycarbonate / acrylonitrile-butadiene-styrene copolymer (PC / ABS) alloy thermoplastic resin composition and a molded product, and in particular to a thermal Plastic resin composition and molded article. Background technique [0002] Polycarbonate / acrylonitrile-butadiene-styrene copolymer (PC / ABS) alloy is a non-crystalline thermoplastic resin, which has excellent impact strength, heat resistance, high rigidity and other properties, and is widely used in 3C home appliances, automobiles, electronics and other fields. Since it needs to be used in various special and complex environments, including places with low temperature, the low temperature performance of the material itself must meet higher requirements. Therefore, in these occasions, PC / ABS alloys require high low temperature resistance to ensure product performance and safety, especially for helmets, sports equipment, suitcases and other applications.
