Abstract

PURPOSE: To form a porous substance suitable as a column packing for liquid chromatography, by suspension-copolymerizing an alkenyl ester of benzenepolycarboxylic acid, divinylbenzene and a styrene in an aqueous medium.
CONSTITUTION: The following components are suspension-copolymerized in an aqueous medium in the presence of a polymerization initiator (e.g., benzoyl peroxide): (A) alkenyl ester of a benzenepolycarboxylic acid of formulaI, wherein R is a 3W10C alkenyl and n is 2W3, (e.g., tri-2-propenyl 1,2,4-benzenetricarboxylate), (B) divinylbenzene (preferably o- or p-) and (C) (alkyl)styrene of formula II, wherein R1 is a 1W6C alkyl and m is 0 or 1, (e.g., ethylstyrene).
