Abstract

Molded products with improved dimensional stability and surface property can be obtained by in-mold curing of a polymerizable composition containing unsaturated urethane of a specified structure, alkyl (meth)acrylate, and a thermoplastic macromolecular compound capable of dissolving in or swelling by impregnating alkyl (meth)acrylate. These components are contained at specified weight ratio. The mold is initially at temperature 30.degree..about.120.degree. C. and the curing is effected in the presence of a radical initiator.
