    Patent number: 4883719
    Abstract: This invention pertains to a method of surface impregnation of wood articles with a plastic and to the resulting wood articles. The method includes treating dried, finished wood articles comprising the steps of degassing the wood to a specified partial pressure, soaking the degassed wood at atmospheric pressure in a diallyl o-phthalate monomer-prepolymer solution for a specified time and polymerizing in the range of 200-210 deg. F in a forced air oven. The cured samples can then be buffed to obtain the desired finish.
