Title:
REINFORCED AROMATIC VINYL COPOLYMER COMPOSITION AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/076967
Kind Code:
A1
Abstract:
Disclosed in the present invention are a reinforced aromatic vinyl copolymer composition and a use thereof, comprising the components of: an aromatic vinyl copolymer 20.0-90.0 parts, a flow promotor 2.0-60.0 parts, a reinforcing agent 5.0-40.0 parts, wherein the flow promoter consists of 60-90% crystalline polyester and 10-40% non-crystalline transparent polyester. The present invention adds a compound material of crystalline polyester and non-crystalline polyester to a reinforced aromatic vinyl copolymer composition as a flow promoter, said compound material having a low viscosity during a melting process. Thus, the flowability of the reinforced aromatic vinyl copolymer composition, when melted, may be significantly improved, such that the polyamide resin may form a skin layer in an injection molding process, and the aromatic vinyl copolymer and a glass fiber material may form a core material. Such a typical skin/core structure may effectively prevent glass fiber from overflowing, and allow the surface of an injection molded part to exhibit a high level of glossiness.
