ADDITIVE COMPOSITION AND PROCESS FOR USING THE SAME

摘要

An additive composition comprises a wax and a nucleating agent. The nucleating agent can be dispersed in the wax. A process for producing a nucleated polymer comprises the steps of (a) providing a reactor; (b) providing an additive composition comprising a wax and a nucleating agent; (c) providing an extruder; (d) reacting in the reactor a reactant mixture comprising an olefin monomer and hydrogen to produce a polyolefin polymer; (e) collecting and recovering the polyolefin polymer produced by the reaction; (f) conveying the polyolefin polymer to the extruder; (g) conveying the additive composition to the extruder; and (g) extruding the polyolefin polymer and the additive composition to produce a nucleated polymer composition.

1. An additive composition comprising:
(a) a wax, the wax being present in the additive composition in an amount of about 60 wt. % or more based on the total weight of the additive composition; and (b) a nucleating agent, wherein the nucleating agent is dispersed in the wax.
