Abstract
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 ##STR1## wherein R 2 and R 3 are each independently alkyl or aryl optionally substituted with lower alkyl; R 4 is hydrogen or R 2 ; R 7 is R 2 or Z 1 ; Z 1 is --CH 2 CHA--(CH 2 ) r Si(R 1 ) 3 ; Z and Z 2 are each independently --CH 2 CHA--(CH 2 ) r Si(R 1 ) 3 or (R 9 ) n Si(H) 3-n ; R 9 is alkyl, alkoxy, phenoxy or aryl optionally 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 R 1 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.
