Abstract: Disclosed is a process includes providing (A) an ethylene/MOCOS copolymer composed of (i) units derived from ethylene, (ii) from 0.01 wt % to 0.5 wt % units derived from a comonomer, and (iii) optionally units derived from a termonomer. The comonomer is a monocyclic organosiloxane (MOCOS) of formula (I) [R1, R2SiO2/2]n wherein n is an integer greater than or equal to 3, each R1 is independently a (C2_C4) alkenyl or a H2C═C (R1a)—C(═O)—O—(CH2)m_ wherein R1a is H or methyl; m is an integer from 1 to 4; and each R2 is independently H, (C1_C4) alkyl, phenyl, or R1. The process includes mixing (B) a free radical initiator with (A) the ethylene/MOCOS copolymer to form a mixture, heating the mixture, and forming a crosslinkable ethylene/MOCOS copolymer composition having a gel content greater than 70%.

Abstract: A method of making a homogeneous mixture of polyolefin solids and an organic peroxide 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 organic peroxide for a period of time sufficient to substantially intermix the polyolefin solids and the organic peroxide 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.
