ABSTRACT:
There is disclosed a process for the functionalization of polymeric resins, wherein a halo-methylated resin, with a crosslink density of at least 4 percent is reacted with an alkyllithium wherein the alkyl radical is 1 to 12 carbon atoms; followed by a reaction to produce a polymeric material having a desired pendant functionality. Materials produced from the process of this invention have utility as intermediates in the production of polymer-bound catalysts and exchange resins.
