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) [R, RSiO]wherein n is an integer greater than or equal to 3, each Ris independently a (CC) alkenyl or a HC═C (R)—C(═O)—O—(CH)wherein Ris H or methyl; m is an integer from 1 to 4; and each Ris independently H, (CC) alkyl, phenyl, or R. 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%.

Crosslinked polymers of ethylene and monocyclic organosiloxane and process

The present disclosure relates to an encapsulant film made from a curable composition comprising: (A) a polyolefin polymer; (B) an organic peroxide; (C) a silane coupling agent; and (D) a co-agent comprising a monocyclic organosiloxane of formula (I).
