Abstract

In moulding organic liquids containing the group CH2=CX, where X is hydrogen or an organic radical, such as methyl methacrylate, by polymerization in relatively narrow rigid moulds of constant volume, a small quantity of a substance having a retarding action on the polymerization reaction is introduced around or near the edges of the mould so that the material adjacent is kept soft and can follow the inward contraction of the mass on polymerization. The retarding substance may be sulphur, a polyhydric phenol, or rubber, and may be applied as a strip or lining, or by paper or fabric impregnated therewith.
