Abstract:
1. A process for preparing a polymer of the formula wherein m is an integer of 0 or 1, X is a halogen atom which is chlorine, bromine, or iodine, A is wherein R is an alkyl group, an aryl group, or mixtures thereof, or mixtures thereof, B is  —(CH 2 ) v —, wherein v is an integer of from 1 to about 20, wherein t is an integer of from 1 to about 20, wherein u is an integer of from 1 to about 20, wherein R 1 and R 2 each, independently of the other, are alkyl groups, aryl groups, or mixtures thereof, and p is an integer of 0 or 1, wherein b is an integer of 0 or 1, wherein (1) Z is or wherein c is 0 or 1; (2) Ar is (3) G is an alkyl group selected from alkyl or isoalkyl groups containing from about 2 to about 10 carbon atoms; (4) Ar′ is (5) X is  —O—, wherein s is 0, 1, or 2, and (6) q is 0 or 1; or mixtures thereof, and n, e, and f are each, independently of the others, integers representing the number of repeating monomer units, wherein e may be 0 and wherein n and f are each at least 1, said process comprising (A) providing a first reaction mixture which comprises (i) a first solvent, (ii) a compound of the formula wherein Y is a chlorine atom or a fluorine atom, (iii) a compound of the formula and (iv) optionally, a compound of the formula (B) heating the first reaction mixture and removing generated water from the first reaction mixture, thereby effecting a polymerization reaction and forming an intermediate polymer of the formula (C) providing a second reaction mixture which comprises (i) a second solvent, (ii) the intermediate polymer, and (iii) a N-halosuccinimide containing a halogen atom, wherein the halogen atom in the N-halosuccinimide is the same as the halogen atom that is X; and (D) heating the second reaction mixture, thereby effecting a polymerization reaction and forming a polymer of the formula
