Incorporation of functional groups in polymers

Abstract From the Canadian patent

A monomer exhibiting polar functionality such as through a hydroxyl group or other functional group is protected during polymerization in the presence of highly active catalysts by the use of a protective alkyl silane group which is removed after polymerization to restore the functionality of the group. The polymer thus made will have functional groups on its backbone; the functional groups may be reacted with conventional dyes and/or may perform other functions and enter reactions with other reactive compounds. New copolymers are disclosed to be made in Ziegler-Natta systems.
