Abstract: A method of making a homogeneous mixture of polyolefin solids and carbon solids without melting the polyolefin solids 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 carbon solids for a period of time sufficient to substantially intermix the polyolefin solids and the carbon solids together while maintaining temperature of the heterogeneous mixture below the melting temperature of the polyolefin solids, thereby making the homogeneous mixture without melting the polyolefin solids.

Abstract: A copolymer of ethylene and hydrolysable silane includes from 0.1 wt % to 5.0 wt % hydrolysable silane groups and has a Mz(abs)/Mw(abs) of less than or equal to 9.5; a ratio of Mz(abs)/Mw(abs) to polydispersity of less than or equal to 1.5; a polydispersity of 6.6 or greater; a Density×Polydispersity of 6.0 or greater; or an Amorphous Content at Room Temperature×Polydispersity of 360 or greater. Methods for forming a moisture-crosslinkable polymer composition include forming a copolymer of ethylene and hydrolysable silane at a polymerization temperature of greater than or equal to 180° C. to less than or equal to 400° C. at a pressure from 5,000 psi to 50,000 psi; and adding a silanol condensation catalyst to the copolymer of ethylene and hydrolysable silane.

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.
