PURPOSE:To prepare a new basic crosslinked copolymer useful as adsorbents, anion exchange resins, etc. wihtout aggregation of particles and formation of foams, by polymerizing a monomer mixture containing a dialkyl-substituted aminoethylstyrene and a crosslinkable monomer. CONSTITUTION:A basic crosslinked copolymer having 10-96 wt. % the structural unit II and/or III (R3 is 1-8C alkyl) and a crosslinked main chain, wherein the amount of the crosslinked part is 2-80 wt.%, is prepared by polymerizing a monomer mixture comprising (A) 10-96 wt.% of a dialkyl-substituted aminoethylstyrene I (R1 and R2 are 1-8C alkyl) and (B) 2-80 wt.% of a crosslinkable monomer, e.g. divinylbenzene, etc.. EFFECT:The use of toxic chloromethyl ether can be avoided. |
