Abstract
518,461. Resinous condensation products. GAUNT, J. G. (Laucks, Inc., I. F.). Oct. 3, 1938, No. 28708. [Class 2 (iii)] [Also in Group VIII] Grain-raising of cut wood surfaces is prevented by impregnating to a depth of at least 0.002 inch with a heat polymerized #-eleostearic acid compound dissolved in a water immiscible volatile solvent, the solid content of the solution being less than 40,per cent. and its viscosity being between 50 and 100 seconds (Saybolt universal 70‹ F.). Solutions containing heat-polymerized tung oil alone may be used or the oil may be treated in the presence of or by reaction with a modifying agent such as glycerine, linseed, perilla, soya bean, or cotton seed oils, rosin copal and kauri resins, ester gum, coumarone, and indene resins and oil soluble phenolic and alkyd resins. In particular tung oil modified alkyd resins may be used. Oiticica or po-yoak oil may also be used. Polymerization is effected at 250‹ C. to 310‹ C. Suitable solvents include benzol, toluol, turpentine, carbon tetrachloride, mineral spirits, dipentene, petroleum thinners and hydrogenated naphtha. Driers and oil-soluble fungicides such as creosote, o-phenyl-phenol, chlor-ophenyl-phenol, 2-4-5 trichlorphenol, and tetra and penta chlorphenol, may be added. In examples (2) rosin is added to tung oil heated to 150‹ C. and the mixture held at 300‹ C. till foaming ceases after which it is cooled and thinned with a petroleum distillate ; (3) glycerine is gradually added to tung oil or its fatty acid heated to 235‹ C., after which phthalic anhydride is added and the mixture held at 235‹ C. Solvent is added and the solution, cooled.
