PURPOSE:The titled composition keeping improved workability for a long period free from rise in viscosity, obtained by dissolving a metallic salt of specific 2-dibutylamino-4,6-dithiol-s-triazine in polypropylene oxide. CONSTITUTION:A metallic salt of a 2-dibutylamino-4,6-dithiol-s-triazine shown by formula I (M1 and M2 are H, Na, K or Li but not H at the same time) is dissolved in polypropylene oxide shown by formula II (n is 1-30) to give preferably 25-45wt% solution. 100pts.wt. pasty polyvinyl chloride is blended with 0.5-10pts.wt. metallic salt of 2-dibutylamino-4,6-dithiol-s-triazine. |
