Abstract

본 발명은 비닐 방향족 화합물에 개시제, 유화제, 분자량 조절제 및 그라프팅제를 투여하여 유화중합시켜 비닐 방향족 화합물의 중합체를 제조하고, 연속하여 여기에 비닐 방향족 화합물 및 이와 공중합 가능한 비닐 시안화합물을 투여하여 유화 중합시켜 블럭 공중합체 또는 브렌치 공중합체 형태의 열가소성 수지를 제조함을 특징으로하는 대랑제조에 적합한 열가소성 수지의 제조방법을 제공한다.The present invention is prepared by polymerizing a vinyl aromatic compound by emulsion polymerization by administering an initiator, an emulsifier, a molecular weight modifier, and a grafting agent to a vinyl aromatic compound, followed by emulsion polymerization by administering a vinyl aromatic compound and a vinyl cyan compound copolymerizable therewith. The present invention provides a method for producing a thermoplastic resin suitable for bridging, characterized in that the thermoplastic resin is prepared in the form of a block copolymer or a branch copolymer.
