摘要： A vulcanizable composition comprising a sulfur vulcanizable rubber, a sulfur vulcanizing agent, an accelerating agent selected from the group consisting of non-thiazole sulfenamide accelerators in an amount effective to not substantially inhibit vulcanization and an amount effective to improve the hardness stabilization of said rubber upon vulcanization of a hardness stabilization agent comprising a pyrimidine derivative. A method of improving the hardness stabilization of a composition comprising a sulfur vulcanizable rubber by adding to said composition the accelerators and pyrimidine derivative.

摘要： Provided are polypropylene-based films and sheets having good ultraviolet shieldability. While being stored, the films and the sheets are free from additive bleeding, and their outward appearance is kept all the time good. The films and the sheets are formed from a composition comprising 100 parts by weight of a polypropylene-based resin and from 0.01 to 5 parts by weight of one or more compounds selected from the following (A) to (D): (A) 2-(2-hydroxy-5-t-octylphenyl)benzotriazole, (B) 2-(2H-benzotriazol-2-yl)-6-dodecyl-4-methylphenol, (C) specific triazine compounds, and (D) specific methylene-bisphenols.
