ABSTRACT:
New polymers are disclosed to be made in supported Ziegler-Natta systems. They include monomers exhibiting polar functionality such as through a hydroxyl group or other functional group 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 typical polymer thus made is a polyolefin having 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.
