Abstract

The invention relates to a process for the production of mouldings of crosslinked polymers by processing (moulding) of uncrosslinked copolymers of vinyl compounds and polymerisable silane compounds having 1 to 3 hydrolysable groups to give the desired mouldings and crosslinking of the copolymers in the mouldings by aftertreatment of the mouldings with acidic or alkaline aqueous solutions.
