2. The process of claim 1 wherein said monomer is polymerized in situ by means of ionizing radiation.
3. The process of claim 1 wherein said monomer contains from about 0.01 to about 0.5 weight per cent of a free radical polymerization catalyst and is polymerized in situ by subjecting the monoMer impregnated wood to heat to initiate polymerization.
4. The process of claim 1 wherein said organic free radical polymerizable monomer is selected from the group consisting of methyl methacrylate, vinyl chloride, acrylonitrile, vinyl acetate, styrene, and mixtures thereof.
5. The process of claim 1 wherein said drying oil or semi-drying oil is selected from the group consisting of soybean, linseed, tall, tung, perilla, oitica, cottonseed, corn, sunflower, and dehydrated castor oil and mixtures thereof.
6. The process of claim 1 wherein the drying oil is doubly boiled linseed oil.
7. The process of claim 1 wherein said composition is applied to said composite in a volumetric amount of from about 0.5 to about 2.0 gallons per 6,000 square feet of composite surface.
8. The process of claim 1 wherein said penetrating solution further comprises an organic hydrocarbon solvent, and the volume ratio of oil to solvent is from about 3:1 to 1:3.
9. The process of claim 8 wherein the solvent is selected from the group consisting of naphtha, Stoddard solvent, and petroleum ether.
10. The process of claim 1 wherein said penetrating solution further comprises from about 0.01 to about 1 weight per cent of a siccative agent.
11. The process of claim 10 wherein said siccative agent is selected from the group consisting of cobalt, lead, zinc, and manganese salts and mixtures thereof.
12. The process of claim 10 wherein said monomer is methyl methacrylate, said drying oil is doubly boiled linseed oil which is applied to said wood composite in a continuous manufacturing process in a volumetric amount of from about 0.5 to about 2.0 gallons per 6,000 square feet of composite surface, and the composite is thereafter buffed.
13. A wood plastic article having a surface having permanent gloss, water spotting resistance, and stain resistance wherein said article is prepared by impregnating wood with an organic free radical polymerizable monomer, polymerizing the resultant monomer-impregnated wood in situ and thereafter coating the surface of the resultant polymer-impregnated wood composite with a penetrating solution comprising a drying oil or semi-drying oil.
