A manufacturing method of the present invention obtains: a copolymer organic solvent solution or copolymer organic solvent slurry where a concentration of a copolymer is 5 to 50 wt% by mixing an acrylonitrile-butadiene-styrene copolymer or a hydrogenated product with an organic solvent; an epoxidized copolymer solution by epoxidizing an unsaturated carbon bond present in the butadiene in the copolymer using an epoxidizing agent for the copolymer organic solvent solution or the copolymer organic solvent slurry; and an epoxidized acrylonitrile-butadiene-styrene copolymer by removing the organic solvent from the epoxidized copolymer solution. 본 발명 제조방법은 아크릴로니트릴-부타디엔-스티렌계 공중합체 또는 그 수첨물을 유기용제와 혼합하여, 상기 공중합체의 농도가 5∼50중량%인 공중합체 유기용제용액 또는 공중합체 유기용제슬러리를 얻고, 상기 공중합체 유기용제용액 또는 공중합체 유기용제슬러리를 에폭시화제를 사용하여 상기 공중합체내의 부타디엔에 존재하는 불포화 탄소결합을 에폭시화하여 에폭시화 공중합체용액를 얻고, 이 에폭시화 공중합체용액으로부터 유기용제를 제거함으로써 에폭시화 아크릴로니트릴-부타디엔-스티렌계 공중합체를 얻는다.
