Title
(EN) ETHYLENE-VINYLACETATE COPOLYMER AND PREPARATION METHOD THEREFOR
(FR) COPOLYMÈRE D’ÉTHYLÈNE-ACÉTATE DE VINYLE ET SON PROCÉDÉ DE PRÉPARATION
(KO) 에틸렌 비닐아세테이트 공중합체 및 그 제조방법
Abstract
(EN)
The present invention provides: an ethylene-vinylacetate copolymer which has a high degree of crosslinking even with a reduced amount of crosslinking agent used, by control of, during polymerization, a temperature difference in an autoclave reactor and the input ratio of initiator; and a preparation method therefor.
(FR)
La présente invention concerne : un copolymère d'éthylène-acétate de vinyle, qui présente un degré élevé de réticulation même avec l'utilisation d'une quantité réduite d'agent de réticulation, en régulant la différence de température et la proportion d'initiateur introduite dans un réacteur autoclave au moment de la polymérisation ; et son procédé de préparation.
(KO)
본 발명에서는 중합시 오토클레이브 반응기내 온도차 및 개시제 투입 비율을 제어함으로써 감소된 가교제 사용량으로도 높은 가교도를 갖는 에틸렌 비닐아세테이트 공중합체 및 그 제조방법을 제공한다.
