Abstract
High molecular weight non cross-linked polyfluoroalkoxyphosphazenes containing some unsaturated groups can be cured (i.e. cross-linked) by contact with a catalyst consisting essentially of platinum, a platinum halide or a haloplatinic acid or their hydrates (e.g. chloroplatinic acid hydrate).
Claims15
A process for curing a high molecular weight substantially linear polyorganophosphazene having substituent groups bonded to phosphorus, at least a portion of said substituent groups being olefinically unsaturated groups, said process comprising contacting said polyorganophosphazene with a small effective amount of a platinum halide, haloplatinic acid or hydrates thereof or mixtures thereof.
