Abstract: A foamable polymer composition comprising a crosslinkable polymer, a crosslinking peroxide compound, and a chemical blowing agent comprising a functionalized particulate bicarbonate containing at least one additive. The additive may be selected from the group consisting of a fatty acid, a rosin acid, any derivative thereof, and salts thereof; or any combinations thereof, such as comprising abietic acid, dihydroabietic acid, neoabietic acid, a rosin acid ester, linoleic acid, or mixtures thereof. The particulate bicarbonate may be preferably functionalized by spray-coating, extrusion or co-grinding with at least one additive. The functionalized particulate bicarbonate may further comprise 0.1-5 wt % silica. A process for manufacturing a foamed crosslinked polymer, such as EVA and/or crosslinked polyolefins, and a foamed crosslinked polymer obtained by such process.

Abstract: Composition comprising a) a polymer comprising recurring units derived from vinylidene fluoride monomer and at least one monomer carrying at least one functional group selected from carboxyl groups, ester groups and hydroxyl groups, and b) a microporous adsorbent carbon material having a specific surface area (BET) of at least 700 m2/g, a pore volume in the range of from 0.1 to 0.7 m3/g, at least 60% of said pore volume being formed by micropores having a pore radius of 2 nm or less.
