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%.
