Abstract:
1. A method for preparing a polymer composition for film formation comprising a step of hydrolysis and condensation of two or more hydrolysable silane compounds in the presence of an anionic ion exchange resin wherein the hydrolysable silane compounds are selected from the group consisting of Formulae (1) and (2): wherein R 1 , R 3 and R 4 each independently represents a monovalent hydrocarbon group which may have a substituent; R 2 , R 5 and R 6 each independently represents a hydrolyzable group; R 7 represents a straight-chain, branched or cyclic divalent aliphatic hydrocarbon radical having 1 to 6 carbon atoms which may be saturated or unsaturated, or a divalent aromatic hydrocarbon radical having 6 to 12 carbons; “a” represents an integer of 0 to 3; and “b” and “c” each represents an integer of 1 or 2; and wherein at least one of the hydrolysable silane compounds is selected from Formula (2), and wherein when R 7 is a two carbon straight-chain, branched or cyclic divalent aliphatic hydrocarbon radical, “b” and “c” each represent an integer of 2.
