The polymerizable dimethicone copolyol macromer composition is synthesized by reacting itaconic anhydride with dimethicone copolyol. During the reaction, itaconic anhydride spontaneously isomerizes to citraconic anhydride, which is then esterified with dimethicone copolyol. The resulting macromer can be copolymerized with an olefinically unsaturated monomer. Polymers containing macromer repeat units are flexible, lubricious, fixative, water-repellent, glossy, surface-modifying, and surface active in a variety of applications, including personal care, textile and industrial formulations Useful for imparting properties. |
