ABSTRACT:
Methyl- and phenyl-containing fluorosilicone terpolymeric fluids over the range of 30 cps to 200,000 cps are effective as additives for various uses. Over the range of 16,000 to 200,000 cps, the fluids are effective as additives in promoting a finger transferable self-bleed of lubricant in fluorosilicone-containing heat-curable rubber compositions, even after a post-bake of the composition. Over the viscosity range of 30 cps to 1000 cps, the fluids are useful in personal care and cosmetic products as water and oil repellency additives. Methods of ring opening polymerization are used to produce the terpolymeric fluids from cyclic reactants.
