Abstract: What is described herein is a liquid U.V. stabilizer composition and process for effectively surface modifying a PVC resinous body to provide a stabilizing amount of U.V. stabilizer within the surface region of the body within a predetermined solu­tion contact time without leaving an appreciable amount of solvent therein or stabilizer on the surface of the body, and without af­fecting the surface appearance of the modified surface of the body.
In one form of the invention, the U.V. stabilizer com­position comprises about 10 to 50 wt/vol%, preferably 15 to 35 wt/vol%, of a U.V. stabilizer dissolved in a mixture of methylene chloride and a liquid fluorochloro hydrocarbon. Suitably the methylene chloride component of the solvent mixture comprises about 40 to 99%, preferably about 50 to 85%, and the fluorochloro hydrocarbon component comprises about 1 to 60%, preferably about 15 to 50%, of the solvent mixture. A preferred fluorochloro hydrocarbon is 1,1,2-trifluoro-1,2,2-trichloroethylene.

Abstract translation: 这里描述的是液体U.V. 稳定剂组合物和方法，用于有效地表面改性PVC树脂体以提供稳定量的U.V. 稳定剂在预定的溶液接触时间内的体内表面区域内，而不会在体内表面上留下可观量的溶剂或稳定剂，并且不会影响体表的改性表面的表面外观。 在本发明的一种形式中， 稳定剂组合物包含约10至50wt / vol％，优选15至35wt / vol％的U.V. 溶解在二氯甲烷和液体氟氯烃的混合物中的稳定剂。 适当地，溶剂混合物的二氯甲烷组分包含约40至99％，优选约50至85％，氟氯烃组分占溶剂混合物的约1至60％，优选约15至50％。 优选的氟氯烃是1,1,2-三氟-1,2,2-三氯乙烯。
