ABSTRACT:
The present invention relates to (meth)acrylamide monomers of the formula:wherein R is H or CH3, R1is selected from H, substituted and unsubstituted alkyl groups having 1 to 8 carbon atoms, substituted and unsubstituted benzene and toluene groups andand R2, R3and R4are independently selected from alkyl groups having 1 to 8 carbon atoms, substituted and unsubstituted benzene and toluene groups, and —OSiR5R6R7wherein R5, R6and R7are independently selected from the group consisting of straight or branched alkyl groups having 1 to 4 carbon atoms. Polymers made therefrom are also disclosed.
