Abstract: A method of making a homogeneous mixture of polyolefin solids and a particulate solid additive without melting the polyolefin solids or the particulate solid additive during the making. The method comprises applying acoustic energy at a frequency of from 20 to 100 hertz to a heterogeneous mixture comprising the polyolefin solids and the particulate solid additive for a period of time sufficient to substantially intermix the polyolefin solids and the particulate solid additive together and while maintaining temperature of the heterogeneous mixture below the melting point of the at least one particulate solid additive and below the melting temperature of the polyolefin solids, thereby making the homogeneous mixture without melting the polyolefin solids or the at least one particulate solid additive.

Abstract: The process disclosed includes an extruder under extrusion conditions at a temperature from 50° C. to 250° C., and a polymer composition. The polymer composition includes (A) greater than or equal to 5 wt % of a silane functionalized olefin-based polymer with first melting temperature, Tm1, (B) optionally, a nonsilane functionalized polyolefin, with second melting temperature, Tm2, (C) a highly effective silanol condensation catalyst (HEC), (D) a permeability modifier, and (E) optionally, a scorch inhibitor. The process includes introducing a physical blowing agent into the polymer composition to form a foamable composition. The foamable composition is cooled to a foaming temperature from 10° C. less than to 10° C. greater than Tm1. The foamable composition from an extruder exit die to form a foam composition. The foam composition is moisture cured to form a crosslinked foam composition having a density from 0.010 g/cc to 0.200 g/cc, and a gel content from 5% to 100%.
