Title:
METHOD FOR PREPARING AROMATIC VINYL-UNSATURATED NITRILE-BASED COPOLYMER AND AROMATIC VINYL-UNSATURATED NITRILE-BASED COPOLYMER PREPARED THEREBY
Document Type and Number:
WIPO Patent Application WO/2017/164507
Kind Code:
A1
Abstract:
The present invention provides a method for preparing an aromatic vinyl-unsaturated nitrile-based copolymer and an aromatic vinyl-unsaturated nitrile-based copolymer prepared using the method, wherein, in the preparation of an aromatic vinyl-unsaturated nitrile-based copolymer, of which the content of unsaturated nitrile-based monomer-derived structural units in a copolymer is 22-30 wt%, the contents of oligomers and unreacted monomers are decreased, and as a result, excellent heat resistance and remarkably improved surface quality can be obtained, and particularly, when a product is used in a closed high-temperature environment, the residues generated on a surface of the product and the mold deposits generated during injection molding can be reduced.
