Novel partially silylated polyvinylphenol polymers of the Formula (I) are disclosed: <IMAGE> Formula (I) wherein X is H or CH3; R is -OH or <IMAGE> wherein R1 is -O or -O(CH2)n, n is 1 to 4, and R2, R3 and R4 are independently selected from 1-4 carbon alkyl, aryl or benzyl, and wherein the average molecular weight of the silylated polymer is from about 2,700 to 22,000 and the average percent by weight silicon is from about 3% to 12%. This invention also relates to blends of such polymers to yield a polymer having a predetermined average molecular weight and percent by weight silicon.
