definición de 촉매중합 en el diccionario coreano
Polimerización del catalizador La reacción de polimerización se inicia con una pequeña cantidad de material activo (catalizador o iniciador). Polimerización radical, polimerización iónica, polimerización de coordinación y polimerización de transferencia de carga por la especie activa (especie activa) generada a partir del catalizador. Se utiliza para la polimerización de adición de unidades de vinilo o para la polimerización de apertura de anillo de unidades de anillo. En la polimerización catalítica, el catalizador utilizado es importante porque afecta en gran medida la velocidad de polimerización, la estructura del polímero resultante y diversas propiedades físicas. 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.
