Compositions comprising specific disodium hexahydrophthalate(HHPA) salts in combination with acid scavengers (such as organic calcium salts or dihydrotalcite complexes) that provide highly desirable and effective nucleating properties within polymer articles (such as polyolefins) are provided. Surprisingly, such a combination of HHPA salt and acid scavenger provides high crystallization temperatures, low haze, and / or high flexural modulus to the finished polymer product. Other sodium salt polymer nucleators (such as sodium benzoate) deleteriously react with calcium organic salt acid scavengers such that characteristically high crystallization temperatures are drastically reduced when in combination with calcium salts (such as calcium stearate). Also, sodium benzoate when combined with dihydrotalcite acid scavengers produce extremely high haze levels in the finished target polymer article, whereas the inventive compositions surprisingly reduce haze. The finished polymer articles comprising such an inventive composition are also contemplated within this invention.

Specific methods of inducing high nucleation rates in thermoplastics, such as polyolefins, and particularly, though not necessarily, polypropylenes, through the introduction of two different compounds that are substantially soluble within the target molten thermoplastic resin (such as, as one non-limiting example, an added compound including at least one acid group and an added organic salt) are provided. Such introduced components react to form a nucleating agent in situ within such a target molten thermoplastic resin which is then allowed to cool. Preferably, one compound is an acid, preferably bicyclic (i.e., two cyclic systems sharing at least three carbon atoms) or monocycloaliphatic (i.e., a single, saturated ring system) in nature, such as, without limitation, bicyclo[2.2.1]heptane dicarboxylic acid or hexahydrophthalic acid, and the other compound is an organic salt, such as a carboxylate, sulfonate, phosphate, oxalate, and the like, and more preferably selected from the group consisting of metal C8-C22 esters. Such a production method thus provides a manner of generating in Situ the desired nucleating agent through reaction of such soluble compounds.
