PURPOSE: A stabilizer having extremely improved stability to heat and to oxidation, good volatility and resistance to color change by heating, consisting of a specific of a specific isocyanuric acid and a specified sulfur compound. n CONSTITUTION: (A) 1,3,5-Tris{2-[3-(3-t-butyl-4-hydroxy-5-methylphenyl)propionyloxy]ethyl} isocyanuric acid is blended with (B) a sulfur compound shown by the formula (R 1 is 3W18C alkyl; R 2 and R 3 are H, or 1W6C alkyl) in a weight ratio of A:B=1:0.5W15, preferably 1:2W6. 3,9-Bis(2-dodecylthioethyl)-2,4,8,10-tetraoxaspiro[5,5]undecane is used as the component B. Especially polypropylene is effective as a synthetic resin to be blended, 100pts.wt. resin is blended with 0.05W 1pt.wt. total amount of the blend. n COPYRIGHT: (C)1985,JPO&Japio |
