Abstract

PURPOSE: To obtain a (meth)acrylate ester polymer for use as contact lens, having improved oxygen permeability, cutting processing characteristics, and dimensional stability, by blending specific amounts of specified (meth)acrylate, which are afterwards polymerized.
CONSTITUTION: A (meth)acrylate ester polymer comprising 20W100wt% of at least one selected from the group consisting of (meth)acrylates shown by the formulae I, II, and III (R1 is H or methyl; R2, R3, and R4 are H or 1W6C atomic group; R5, R6 and R7 are H or hydrocarbon ; R8, R9, and R10 are H or hydrocarbon)as a repeating unit. A) 20W100wt% of the (meth)acrylate ester, B) 0W80wt% of methyl (meth)acrylate, and if necessary, C) 0.5W20wt% of hydroxyl group-containing (meth)acrylate are polymerized, for example, in the presence of a peroxide under heating, to give the desired high polymer.
