Claim 0:
1. A foam bead comprising at least one of the following components:
(A) a block composite containing three polymer components
(ai) an ethylene-based polymer having an ethylene content from 10 mol % to less than 90 mol %, based on the total moles of polymerized monomer units in the ethylene-based polymer;
(aii) an alpha-olefin based polymer having an alpha-olefin content of greater than 90 mol %, based on the total moles of polymerized monomer units in the alpha-olefin based polymer; and
(aiii) a block copolymer having an ethylene block and an alpha-olefin block, wherein the ethylene block contains more polymerized ethylene than the alpha-olefin block and the ethylene block of the block copolymer is the same composition as the ethylene-based polymer (ai) and the alpha-olefin block of the block copolymer is the same composition as the alpha-olefin based polymer (aii); and/or

(B) a crystalline block composite containing three polymer components
(bi) a crystalline ethylene-based polymer having an ethylene content of greater than , or equal to, 90 mol %, based on the total moles of polymerized monomer units in the crystalline ethylene-based polymer;
(bii) a crystalline alpha-olefin based polymer having an alpha-olefin content of greater than 90 mol %, based on the total moles of polymerized monomer units in the crystalline alpha-olefin based polymer; and
(biii) a block copolymer comprising a crystalline ethylene block and a crystalline alpha-olefin block, wherein the crystalline ethylene block of the block copolymer is the same composition as the crystalline ethylene-based polymer (bi) and the crystalline alpha-olefin block of the block copolymer is the same as the crystalline alpha-olefin based polymer (bii).
