摘要 |
<p>A stabilizer for synthetic resins, e.g. polyolefins such as polypropylene, of which the effective ingredient is a mixture of 1,3,5-tris{2-[3-(3-t-butyl-4-hydroxy-5-methylphenyl)-propionyloxy]ethyl}isocyanu ric acid (1) and at least one sulfur-containing compound (II) selected from compounds represented by the general formulae (II-I) and (II-2):
(R1 - S - CH2CH2@ - O - CH2 &rparstr& @ C (II-1)
wherein R1 is an alkyl group having 4 to 20 carbon atoms, and
<CHEM>
wherein R2 is an alkyl group having 3 to 18 carbon atoms, and R3 and R4 are selected independently from hydrogen and alkyl groups having 1 to 6 carbon atoms. Preferably the weight ratio (I):(II) is from 1:0.5 to 1:15. </p> |
