Abstract
In an aspect, a composition comprises a hydrocarbyl thermoplastic polymer comprising repeat units derived from an alpha-olefin and a C4-30 cycloalkene; a reactive monomer which is free-radically crosslinkable to produce a crosslinked network; a free radical source; and a functionalized fused silica capable of chemically coupling to the crosslinked network.

A composition comprising:
- a hydrocarbyl thermoplastic polymer comprising repeat units derived from an alpha-olefin and a C4-30 cycloalkene;
- a reactive monomer that is free-radically crosslinkable to produce a crosslinked network;
