Patent ID: 6858697

Claim:
A process for stabilizing a cyclotetrasiloxane against polymerization, the cyclotetrasiloxane having the following formula: wherein R 1-7 are individually selected from the group consisting of hydrogen, a normal, branched or cyclic C 1-10 alkyl group, and a C 1-4 alkoxy group, the process comprising: providing an effective amount of an inhibitor to the cyclotetrasiloxane wherein the inhibitor is selected from 2,4-pentanedione; 1-hexanoic acid; glycerol; acetic anhydride; β-diketones RC(O)CH 2 C(O)R; aliphatic carboxylic acids RCOOH; aliphatic dicarboxylic acids HOOC—(CH 2 ) n —COOH in which 1≦n≦8; phenols C 6 R (6-n) (OH) n in which 1≦n≦5; polyols CH 2 X(CHX) n CH 2 X, in which X=H or OH but at least one X=OH and 1≦n≦8; anhydrides RCH 2 —C(O)—O—C(O)—CH 2 R; hydrodosiloxanes R 3 Si—(O—SiR 2 ) n OSiR 3 , in which 0≦n≦8, all wherein R is individually selected from the group consisting of hydrogen, normal, branched or cyclic C 1-10 alkyl groups; and mixtures thereof.
