Method of manufacturing shaped article of hydrogel

摘要

A method for the manufacture of shaped article of hydrogel is provided. This shaped article of hydrogel is obtained by the polymerization in a mold of a mixture comprising: A. an alkylene glycol mono(meth)acrylate or a monomer mixture consisting preponderantly of an alkylene glycol mono(meth)acrylate, B. a polymer synthesized from a component A and possessing a polymerizable double bond in the molecular unit thereof, C. a water-soluble dipolar aprotic solvent, and D. at least one member selected from the group consisting of (a) water-soluble organic acids, (b) surface active agents, and (c) water-soluble organic substances which are poor solvents or non-solvents of the component B, and having the weight ratio of the component A to the component B in the range of 45:55 to 20:80.
