Abstract
PURPOSE: To obtain the title gel having strength and molecular weight fractionating property suitable as a gel for an aqueous gel chromatography and being especially useful for desalting an aqueous polymer solution by saponifying a copolymer of vinyl ester and diallylidene-pentaerythritol.
CONSTITUTION: A copolymer obtained by copolymerizing (A) vinyl ester 100pts. wt. and (B) diallylidene-pentaerythritol 0.5W80pts.wt. is saponified to provide hard polyvinyl alcohol gel. Therein, a monomer material of (A) having a structure of formula I (R is alkyl) and vinyl acetate with methyl group as R is commonly used. (B) is a compound having a structure of formula II.
