Abstract
The present disclosure provides a process. The process includes (i) crosslinking pellets composed of a silane-grafted ethylene/α-olefin multi-block copolymer (Si-g-OBC) to a gel content from 10% to 80% to form crosslinked Si-g-OBC pellets; and (ii) foaming the crosslinked Si-g-OBC pellets to form crosslinked Si-g-OBC foam beads having a gel content from 10% to 80%.
