A crosslinked polymer having perfluorocyclobutane rings is prepared in a process comprising the steps of: (a) contacting monomers having two dimerizable perfluorovinyl groups; (b) exposing the monomers to sufficient heat and for a sufficient time that a (linear) polymer containing perfluorocyclobutane rings is formed; and (c) exposing the polymer to sufficient crosslinking initiating means and for a sufficient time such that crosslinking occurs. Crosslinked polymers, so prepared are novel and have tensile strength and other physical properties enhanced over the properties of the corresponding linear polymer.
一种具有全
氟环丁烷环的交联聚合物的制备方法包括以下步骤:(a)接触具有两个可二聚的
全氟乙烯基团的单体;(b)将单体暴露在足够的热量和时间下,形成含有全
氟环丁烷环的(线性)聚合物;(c)将聚合物暴露在足够的交联
引发剂和时间下,使交联发生。因此制备的交联聚合物是新颖的,并且具有拉伸强度和其他物理性能,其性能优于相应的线性聚合物。
