    • A thermoplastic composition includes a polyolefin having a polymeric backbone and, associated therewith, one or more ionic compounds having a central metal element and one or more carboxylic acid functional moieties. The thermoplastic composition may be, for example, polyethylene or polypropylene. A method of improving the mechanical properties of thermoplastics includes adding, to a thermoplastic composition having a polymeric backbone, an additive including one or more ionic compounds having a central metal element and one or more carboxylic acid functional moieties, wherein the additive is added to the thermoplastic composition at conditions suitable to associate the one or more ionic compounds to the polymeric backbone. The ionic compounds may be, for example, zinc cinnamate, zinc hydrocinnamate, zinc naphthoate, zinc naphthalene acetate, isophthalic acid zinc salt, and phthalic acid zinc salt, and their equivalents substituting calcium or magnesium instead of zinc as the central metal element, and mixtures thereof.
    • 热塑性组合物包括具有聚合物主链的聚烯烃,并且与其相关联,具有一种或多种具有中心金属元素和一个或多个羧酸官能部分的离子化合物。 热塑性组合物可以是例如聚乙烯或聚丙烯。 改进热塑性塑料的机械性能的方法包括向具有聚合物主链的热塑性组合物中加入包含一种或多种具有中心金属元素和一种或多种羧酸官能部分的离子化合物的添加剂,其中将添加剂加入到 热塑性组合物在适于将一种或多种离子化合物与聚合物骨架缔合的条件下进行。 离子性化合物可以是例如肉桂酸锌,氢化肉桂酸锌,萘甲酸锌,萘乙酸锌,间苯二甲酸锌盐和邻苯二甲酸锌盐,它们的取代为钙或镁而不是锌作为中心金属元素的当量,以及 其混合物。
