Abstract
PURPOSE: To prepare radiation-shielding plastic material having excellent transparency and mechanical properties, by polymerizing a mixture of a specific monomer, e.g. alkyl (meth)acrylate, and organic acids containing a specific unsaturated carboxylic acid in the presence of a lead compound.
CONSTITUTION: A mixture comprising (A) 10W94pts.wt. of one or more vinyl monomers selected from 1W4C alkyl (meth)acrylate, hydroxyalkyl (meth)acrylate, styrene, etc., and (B) 90W6pts.wt. of organic acids containing, as an essential component, an unsaturated carboxylic acid expressed by the formula (R1 and R2 are H or methyl; R3 is 2W7C hydrocarbon), is polymerized in the presence of a lead compound (e.g. lead monoxide) and a radical polymerization initiator. The preferable molar ratio of lead in the lead compound to the whole component (B) is ≤0.5.
