    摘要: A polyolefin composition comprising a polyolefin, and the following components:

    (A) a phenolic compound represented by the formula (I):
    wherein R¹ is hydrogen or an alkyl of 1 to 3 carbon atoms;
    (B) an acrylate compound represented by the formula (II):
    wherein R² is an alkyl of 1 to 5 carbon atoms, R³ is an alkyl of 1 to 8 carbon atoms, R⁴ is hydrogen or an alkyl of 1 to 8 carbon atoms, and R⁵ is hydrogen or methyl; and
    (C) at least one organic phosphorous compound such as bis(2,6-di-t-butyl-4-methylphenyl) pentaerythritol diphosphite.
    This composition is stable against thermal processing, thermal oxidation and discoloration, and it is especially useful for fibers and films. Further incorporation of a polycondensate of dimethyl succinate with 1-(2-hydroxyethyl)-4-hydroxy-2,2,6,6-tetramethylpiperidine is effective to improve the light stability of the composition.

    摘要: A styrene/butadiene copolymer rubber to be used for automobile tires is lowered in its rolling resistance by blending it with carbon black and the following components (A) and (B):

    (A) a dinitrodiamine compound represented by the following formula (I):
    wherein X is a divalent organic group such as an alkylene, R¹ is hydrogen or an organic group such as an alkyl, provided that two nitrogen atoms linking through X may further link through R¹, and R² and R³ are each hydrogen or an alkyl, provided that R² and R³ may conjointly form a ring; and
    (B) a sulfide compound selected from dibenzothiazyl disulfide, tetralkylthiuram disulfide, and alkyl- or hydroxy-substituted phenol sulfide resin. The dinitrodiamine compound (A) and the sulfide compound (B) are added simultaneously to the rubber together with the carbon black in a first kneading step of a high temperature. The resulting rubber composition is lowered in its loss factor (tan δ) at around 60°C as compared with the case where the dinitrodiamine compound (A) is added alone, and it contributes to decrease the rolling resistance of tires made from the rubber composition.
