  Antimony mercaptocarboxylic acid esters are provided having the formula: wherein: R is selected from the group consisting of hydrogen, alkyl having from one to about eighteen carbon atoms and alkylene linked with R2 in a ring having from three to about eight carbon atoms; R2 is selected from the group consisting of alkyl having from one to about eighteen carbon atoms, phenyl, and alkylene linked with R, in a ring having from three to about eight carbon atoms; R3 is selected from the group consisting of hydrogen and alkyl having from one to three carbon atoms; R4 is selected from the group consisting of alkyl, aryl, alkylaryl, alkoxycarbonyl-alkylene and acyloxyalkylene having from three to about twenty carbon atoms, the alkylene having from two to about six carbon atoms; R5 is selected from the group consisting of alkylene and cycloalkylene having from one to about eighteen carbon atoms, and such groups having from one to four hydroxyl groups; Z is a bivalent alkylene group having from one to five carbon atoms and carrying the sulfur in a position alpha or beta to -OOC-; and n is a number from 1 to 3. A process for preparing such antimony compounds is also provided, as well as predecessor intermediates, and stabilizer compositions for polyvinyl chloride resin compositions comprising such antimony compounds, if desired with other polyvinyl chloride resin stabilizers.

  The present invention provides a rubber composition comprising 100 parts by weight of a diene rubber component, 10 to 200 parts by weight of a reinforcing agent, and 0.1 to 15 parts by weight of a fatty acid salt. For example, the diene rubber preferably comprises a diene rubber having a heteroatom-containing polar group, the reinforcing agent preferably comprises carbon black or silica, and the fatty acid salt preferably comprises a metal salt of a C1 to C36 fatty acid. This rubber composition yields a vulcanized rubber showing improvements in heat build-up, tensile strength, abrasion resistance and processability.

  本发明提供了一种橡胶组合物，其中包括 100 份（按重量计）二烯橡胶组分、 10 至 200 份（按重量计）补强剂和 0.1 至 15 份（按重量计）脂肪酸盐。例如，二烯橡胶最好包括具有含杂原子极性基团的二烯橡胶，补强剂最好包括炭黑或二氧化硅，脂肪酸盐最好包括 C1 至 C36 脂肪酸的金属盐。这种橡胶组合物产生的硫化橡胶在蓄热性、拉伸强度、耐磨性和加工性方面均有改善。
