Patent ID: 6921802

Claim:
A method of providing a monomer mixture, the method comprising: providing a reaction mixture comprising at least one cyclic siloxane, at lest one trialkyl siloxane end capping agent, at least one activated unsaturated radical, a catalyst, and reacting the reaction mixture to provide (a) a mixture of polysiloxane prepolymers represented by formula (I) and (II): wherein: each A and A′ is an activated unsaturated radical; A′ is an alkyl group; each R 1 -R 10 is independently an alkyl, fluoroalkyl, alcohol, ether, or fluoroether group having 1-10 carbons, or an aromatic group having 6-18 carbons; each m, n, and p are independently 0 to 200, m+n+p being from about 23 to 200; each a is 1 to 10; and each b is 0 to 10.
