Abstract: The present disclosure provides a pellet. In an embodiment, the pellet includes a body having a first end and an opposing second end. The body is composed of a polymeric material. The body has a length and a diameter (body diameter). A channel having a diameter (channel diameter), extends through the body from the first end to the second end. The pellet has a channel diameter-to-body diameter ratio from 0.05 to 0.45. The present disclosure also provides a process for soaking the pellet in a liquid additive and forming a loaded pellet with the additive in the pellet body.

Abstract: An ethylene-based polymer composition includes units derived from ethylene, units derived from a comonomer, and an 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.
