Abstract
PURPOSE: To prepare a monomer composition containing lead, useful for production of a transparent radiation-shielding material and having a practically high strength and shielding ability, by reacting an organic acid mixture with lead monoxide at a specific ratio in a monomer, e.g. alkyl methacrylate, etc.
CONSTITUTION: (a) An organic and mixture containing an organic acid (I) R1COOH (R1 is 5W20C hydrocarbon residue), (meth)acrylic acid, and if desired an organic acid (II) R2COOH (R2 is 2W4C hydrocarbon residue), is reacted with (b) lead monoxide in (c) a monomer, e.g. alkyl methacrylate, hydroxyalkyl (meth)acrylate, etc. The amount of (b) is 6.5W57wt% on the basis of the whole composition and the ratio of the whole molar number of (a) to the number of gram atom of lead in (b) is ≤4. The amount of (meth)acrylic acid is 3W45wt% on the basis of the whole composition and the total amount of the acids (I) and (II) is 1.1W 60wt%. The amount of (II) is less than that of (I). The molar number (A) of (meth)acrylic acid in 100g of the raw materials and total molar number (B) of the acids (I) and II) are expressed by the equation I or II.
