Abstract:
The process which comprisesA. quaternizing with a quaternizing agent selected from the group consisting of a halogenated alkali or alkaline earth metal salt of a branched or linear C.sub.2 to C.sub.12 monobasic carboxylic acid optionally substituted with a monocyclic aryl radical at a temperature of between about 40.degree. C., and about 140.degree. C., an aqueous suspension of a vinyl pyridine homo- or co- polymer containing repeating units of ##STR11##prepared by a water suspension polymerization in the presence of a suspending amount of a suspension agent, a free radical initiator and optionally an olefinically unsaturated comonomer at a temperature of between about 60.degree. and about 120.degree. C. to produce a quaternized polymer containing repeating units of ##STR12##and B. ##STR13##polymerizing the quaternized product of A. in the presence of a free radical initiator and an olefinically unsaturated comonomer at a temperature between about 60.degree. and about 120.degree. C. to provide the polymerized vinyl pyridine polymer containing repeating units of ##STR14##and the monomer units of the olefinically unsaturated comonomer of B. wherein X is halogen; M is an alkali or alkaline earth metal; each of S and T are independently hydrogen or C.sub.1 to C.sub.2 alky and R is C.sub.1 to C.sub.11 alkylene optionally substituted with monocyclic aryl and recovering the quaternized and subsequently copolymerized product of B.
