Abstract
The process for producing a plastic-like cured woody molding, which comprises applying a pressure necessary for plasticizing at least a woody component at temperature of from 120.degree. C. to 180.degree. C. to a composition comprising (A) an oligoesterified woody material obtained by alternately adding a polybasic acid anhydride and a monoepoxy compound having unsaturated double bond to the hydroxy groups of a woody material and (B) an oligomer obtained from a polybasic acid anhydride and a monoepoxy compound having unsaturated double bond with the addition of (C) a radical polymerization initiator to simultaneously perform the plasticization and crosslinking by the polymerization of the unsaturated double bonds. The plastic-like cured woody moldings thus obtained have dense and glossy surfaces and are particularly excellent in dimensional stability, mechanical properties and heat distortion temperature.
