1. An alkylated crosslinked polymer comprising the reaction product of:

  • a) one or more crosslinked polymers, salts or copolymers thereof characterized by a repeat unit selected from the group consisting of;

    ##STR3## where n is a positive integer and each R, independently, is H or a C1 -C8 alkyl group; and

    b) at least one aliphatic alkylating agent, said reaction product characterized in that;

    (i) at least some of the nitrogen atoms in said repeat units are unreacted with said alkylating agent; and
