ABSTRACT:
A novel class of silicon-containing vinyl polymers having in its molecule at least one constitutent unit of the formula ##STR1## wherein R.sup.1 is a substituted or unsubstituted monovalent hydrocarbon residue; R.sup.2 is ##STR2## R.sup.3 is hydrogen or methyl group; R.sup.4 is a substituent directly bonded to silicon atom and is selected from a substituted or unsubstituted alkylene, or a substituted or unsubstituted alkylene containing hetero atoms; m and n each is a positive integer, which will fulfill the requirement of 2.ltoreq.m+m.ltoreq.4; A is a direct bond, ##STR3## phenylene or substituted phenylene; B is ##STR4## R.sup.5 and R.sup.6 each represents an alkylene, providing that when A is ##STR5## m+n is 2. The present vinyl polymers are very useful in various technical fields including preparation of lens and other molding products, paints and various industrial resins.
