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.

Process for producing plastic-like woody moldings from dibasic acid

There are provided two-part type adhesives composed of two liquid systems, exhibiting marked stabilization without impairing its adhesion property. One liquid system thereof comprises an acrylic monomer, an organic peroxide, and a metal salt of which the metal is an alkali metal, zinc or nickel; the other liquid system comprises an acrylic monomer and a curing accelerator; and at least one of the liquid systems further contains an elastomer.
