GRAFTED SILICONE POLYMER AND PRODUCTS MADE THEREWITH

摘要

The grafted silicone polymer comprises a polymerization product of (a) a mercapto-modified silicone polymer and (b) a radically polymerizable monomer component comprising (meth)acrylic acid and/or a (meth)acrylic acid alkyl ester selected so that the solubility parameter of a polymer obtained only from the radically polymerizable monomer component is at least 9.14 (cal/cm3)1/2, wherein the grafted silicone polymer has a elastic storage modulus of 1 105 Pa or greater at 37° C., 1 Hz and dissolves in decamethylcyclopentasiloxane by 1 weight percent or greater at 23° C.
