Terminal cluster acrylate silicones
First Claim
1. A polyorganosiloxane polymer having a structure represented by one of the formulas
where the R groups are the same or different organic groups other than acrylic groups or groups co-curable therewith;
A is a linear polyorganosiloxane segment containing between 3 and about 50 siloxane repeat units at least 3 of which are acrylic groups containing repeat units represented by the formula ##STR12## where R1 is H or lower alkyl, R2 is alkylene or alkylene;
B is a polyorganopolysiloxane segment represented by the formula ##STR13## where x is an integer of at least 100;
C is A or a triorganosilyl group;
m is an integer of 1 or more; and
n is 3 or 4.
