Abstract
An organofunctional cocyclic siloxane, i.e., a dialkyl, alkyl aminoalkyl cocyclic siloxane, is used to prepare copolymeric siloxane fluids, copolymeric siloxane gums, and terpolymeric siloxanes via three polymerization techniques. In one embodiment, the dialkyl, alkyl aminoalkyl cocyclic siloxane is polymerized using a bulk polymerization technique. In another embodiment, the dialkyl, alkyl aminoalkyl cocyclic siloxane is polymerized using an emulsion polymerization technique. In an additional embodiment, the dialkyl, alkyl aminoalkyl cocyclic siloxane is polymerized using a microemulsion polymerization technique. The dialkyl, alkyl aminoalkyl cocyclic siloxane most preferred is a dimethyl, methyl aminoalkyl cocyclic siloxane.
