Abstract

The present invention relates to (meth)acrylamide monomers of the formula:

wherein R is H or CH₃, R¹ is selected from H, substituted and unsubstituted alkyl groups having 1 to 8 carbon atoms, substituted and unsubstituted benzene and toluene groups and

and R², R³ and R⁴ are independently selected from alkyl groups having 1 to 8 carbon atoms, substituted and unsubstituted benzene and toluene groups, and —OSiR⁵R⁶R⁷ wherein R⁵, R⁶ and R⁷ are independently selected from the group consisting of straight or branched alkyl groups having 1 to 4 carbon atoms. Polymers made therefrom are also disclosed.
