Disodium hexahydrophthalate salt compositions and nucleated polymers comprising such compositions

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