  The resistance to oxidative degradation of polyolefin compositions containing 5 to 50 % by weight of talc and a phenolic antioxidant is improved by adding to the composition a stabilizing amount of poly TDP which is a polyester having an average molecular weight of from about 500 to about 4,000, and having the repeating unit wherein R is selected from divalent radicals such as 1,1-cyclohexanedimethylene; 1,2-cyclohexanedimethylene; 1,3-cyclohexanedimethylene; and 1,4-cyclohexanedimethylene; and preferably being at least partially chain-terminated with a compound such as methanol, ethanol and butanol or acids or their anhydrides such as acetic, butyric and isobutyric acid.

  在含有 5%至 50%（按重量计）滑石粉和酚类抗氧化剂的聚烯烃组合物中加入稳定量的聚 TDP，可提高该组合物的抗氧化降解性能，聚 TDP 是一种聚酯，其平均分子量约为 500 至 4000，具有以下重复单元 其中 R 选自二价基，如 1,1-环己烷二甲亚基；1,2-环己烷二甲亚基；1,3-环己烷二甲亚基；和 1,4-环己烷二甲亚基；最好至少部分以甲醇、乙醇和丁醇等化合物或乙酸、丁酸和异丁酸等酸或其酸酐为链端。

  A method to form a polymeric material is disclosed. The method provides a water immiscible solvent and one or more condensation monomers, where those one or more condensation monomers are essentially insoluble in the water immiscible solvent. The one or more condensation monomers may be either a solid or a liquid at room temperature. The method forms a reaction mixture comprising a suspension of one or more solid condensation monomers, or an emulsion of one or more liquid condensation monomers, in the water immiscible solvent. The method includes heating the reaction mixture to form the polymeric material product. That polymeric material is then separated from said reaction mixture.

  本发明公开了一种形成聚合物材料的方法。该方法提供一种不溶于水的溶剂和一种或多种缩合单体，其中一种或多种缩合单体基本上不溶于不溶于水的溶剂。在室温下，一种或多种缩合单体可以是固体或液体。该方法形成一种反应混合物，该混合物包括一种或多种固体缩合单体在水不溶性溶剂中的悬浮液，或一种或多种液体缩合单体的乳液。该方法包括加热反应混合物以形成聚合材料产品。然后将聚合材料从所述反应混合物中分离出来。
