ABSTRACT:
An initiator compound comprising an aryl or heteroaryl thioacetal including a substituent defined by the formulawhere x is an integer from 1 to about 5, y is an integer from 1 to about 5, the sum of x and y is from about 3 to about 6, α is carbon, sulfur, oxygen, silicon, or an amino group, and each R1is individually hydrogen or a monovalent organic group or where two or more R1groups may join to form one or more rings.
