FDN-1724 HYDROLYZABLE SILICONE POLYMERS ABSTRACT This invention relates to polyfunctional silicone polymers containing one or more alkylene polyfunctional hydrolyzable silyl radicals extended from the siloxy polymer chain, said polymer having the structure Image wherein R2 and R3 are each independently alkyl or aryl optionally substituted with lower alkyl; R4 is hydrogen or R2; R7 is R2 or Z1; Z1 is -CH2CHA-(CH2)rSi(R1)3; Z and Z2 are each independently -CH2CHA-(CH2)rSi(R1)3 or (R9)nSi(H)3-n; R9 is alkyl, alkoxy, phenoxy or aryl optioally substituted with lower alkyl; n has a value of from 0 to 3; x has a value of from 2 to 1000; y has a value of from 1 to 200; p' has a value of from 0 to about 50% of y; A is hydrogen, alkyl or phenyl; r has a value of from 0 to 12; and R1 is hydroxy, acyloxy, halogen, amino, alkoxy, aryloxy or aryloxy substituted with lower alkyl, halogen or acyloxy. The invention also relates to the use of said polymers as surface modifiers, reinforcing coatings and fillers for thermoplastics.
