Abstract
The present invention relates to triorganosiloxy-endblocked poly(methyl(C6-C40alkyl)siloxane)-poly(methyl(aralkyl)siloxane)-poly(methy l(C2-C4alkyl)siloxane) terpolymers. This invention also relates to two different methods of making these terpolymers. The triorganosiloxy-endblocked poly(methyl(C6-C40alkyl)siloxane)-poly(methyl(aralkyl)siloxane)-poly(methy l(C2-C4alkyl)siloxane) terpolymers of this invention are useful as mold release agents in aluminum die cast release agents, rubber lubricants, and as high reflexive index additives for the personal care industry.
