Abstract
Nucleating agent compounds are used in polymers, such as polypropylene, to improve both the properties and processing characteristics of the polymer. Some nucleating agents may be used also as clarifiers to reduce the visual haze in finished polymeric articles, thereby increasing clarity of finished polymeric articles. Compounds of a carboxylate salt which employ a combination of an amide group and a metal cation salt perform well as nucleating agents, and provide substantial clarity benefits in a polymer. Other compounds of the invention may employ metal carboxylate salts in combination with an ester group. In other embodiments of the invention a dimer of such compounds may be employed.
