Patent ID: 7517641

Claim:
A process which comprises reacting a first polymer containing at least some monomer repeat units with haloalkyl substituents thereon and of the formula wherein x is an integer of 0 or 1, R is an alkyl group, a substituted alkyl group, an arylalkyl group, or a substituted arylalkyl group, X is a halogen atom, a, b, c, and d are each integers of 0, 1, 2, 3, or 4, provided that at least one of a, b, c, and d is equal to or greater than 1 in at least some of the monomer repeat units of the first polymer, A is or mixtures thereof, B is wherein v is an integer of from 1 to about 20, wherein z is an integer of from 2 to about 20, wherein u is an integer of from 1 to about 20, wherein w is an integer of from 1 to about 20, or mixtures thereof, and n is an integer representing the number of repeating monomer units, with an epoxy-group-containing alcohol salt, thereby forming a second photopatternable polymer with epoxy groups thereon of the formula wherein R and X are as defined hereinabove, E is an epoxy photosensitivity-imparting group, e, f, g, and h are each integers of 0, 1, 2, 3, or 4, provided that at least one of e, f, g, and h is equal to or greater than 1 in at least some of the monomer repeat units of the polymer, i, j, k, and m are each integers of 0, 1, 2, 3, or 4, provided that the sum of e+i is no greater than 4, the sum of f+j is no greater than 4, the sum of g+k is no greater than 4, and the sum of h+m is no greater than 4.
