définition de 촉매중합 dans le dictionnaire coréen
Polymérisation du catalyseur La réaction de polymérisation est initiée par une petite quantité de matière active (catalyseur ou initiateur). Polymérisation radicalaire, polymérisation ionique, polymérisation par coordination et polymérisation par transfert de charge par les espèces actives (espèces actives) générées à partir du catalyseur. Il est utilisé pour la polymérisation par addition d'une unité vinylique ou pour la polymérisation par ouverture de cycle d'une unité cyclique. Dans la polymérisation catalytique, le catalyseur utilisé est important car il affecte grandement la vitesse de polymérisation, la structure du polymère résultant et diverses propriétés physiques. 촉매중합 중합 개시가 소량의 활성물질(촉매 또는 개시제)에 의하여 행하여지는 중합반응을 말한다. 촉매로부터 생성하는 활성종(活性種)에 의하여 라디칼중합·이온중합·배위중합·전하이동중합 등으로 분류되어 있다. 비닐 단위체의 첨가중합이나 고리 모양 단위체의 고리열림중합에 이용된다. 촉매중합에서는 사용하는 촉매가 중합속도, 생성중합체의 구조, 여러 물성에 큰 영향을 주기 때문에 중요하다.
