Abstract
PURPOSE: To provide title gel which is less shrinkable in an aq. soln. of an electrolyte and useful as a gel for water gel chromatography, obtd. by saponifying a copolymer of vinyl ester and a crosslinker such as triazine cpd. and then crosslinking the resulting product with epichlorohydrin.
CONSTITUTION: (A) 100pts.wt. of vinyl ester is copolymerized with (B) from 0.01 to 10pts.wt. of a crosslinker selected from cpd. having triazine structure of formula I or II (wherein R1,R2,R3 are the same or different gp. and each is a radical of formula III, IV or V) and diallylidenepentaerythritol of formula VI to produce a copolymer which is then saponified. The product is crosslinked with (C) epichlorohydrin to obtain a hydrophilic monionic rigid gel which is less. shrinkable in an aq. soln. of an electrolyte.
