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.
Claims2
A compound of the formula ##STR21## wherein (X) is a connecting hydrocarbyl fragment other than an unsaturated non-cyclic hydrocarbyl, and other than an unsaturated cyclic non-aromatic hydrocarbyl, having from 1 to 20 carbon atoms, and each R is independently selected from alkyl, alkoxy, alicyclic, aryloxy, alkaryl and aryl groups having from 1 to about 20 carbon atoms, provided that the total of carbon atoms in all R's together with all carbons directly attached to the carbon in X connected to an O is at least 5.
4-(dimethyl phenyl siloxy)-1,6-heptadiene.
