Process for preparation of hard and porous polyvinylalcohol gels |
摘要 |
A process for the preparation of hard and porous polyvinylalcohol gels for aqueous gel permeation chromatography, comprises suspension-polymerizing vinyl acetate with diethylene glycol dimethacrylate or glycidyl methacrylate in the presence of a diluent which controls pore size of the product as a crosslinking agent, saponifying the resulting porous polyvinyl acetate gel with an alkali, and subjecting the resulting porous polyvinylalcohol gel to post-crosslinking with epichlorohydrin.
