Abstract
A foam bead is formed from a composition comprising an ionomer comprising, in polymerized form, ethylene, an unsaturated acid comonomer and, optionally, an acrylate comonomer, wherein the unsaturated acid comonomer is at least partially neutralized with a neutralizing agent. A sintered foam structure is formed from foam beads that are formed from above composition.
Claims10
A sintered foam structure formed from foam beads that are formed from a composition comprising:
- an ionomer comprising, in polymerized form, ethylene, an unsaturated acid comonomer, and, optionally, an acrylate comonomer,
- wherein the unsaturated acid comonomer is completely or partially neutralized with a neutralizing agent.
A foam bead formed from a composition comprising:
- (A) an ionomer comprising, in polymerized form, ethylene, an unsaturated acid comonomer, and, optionally, an acrylate comonomer,
- wherein the unsaturated acid comonomer is completely or partially neutralized with a neutralizing agent.
