Abstract: The present invention provides a method of forming a functionalized polymer. The method includes the steps of providing a living lithium polymer and terminating the polymer with an oxazoline compound selected from an organic halide oxazoline and a branched or unbranched vinyl oxazoline compound. The present invention also provides a compounded rubber article wherein carbon black is compounded with a terminated rubber that is the reaction product of a living lithium polymer and such oxazoline compounds.

Abstract: 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.
