Claims5
A composition consisting of fine particulate crosslinked amorphous copolymer selected from the group consisting of ethylene/.alpha.-olefin copolymer and ethylene/.alpha.-olefin/polyene copolymer having an average particle diameter of 0.2 to 50 .mu.m and containing hot toluene insolubles of 15% by weight or more.
A latex composition containing a polymer component consisting of a cross-linked amorphous ethylene/.alpha.-olefin copolymer or a cross-linked amorphous ethylene/.alpha.-olefin/polyene copolymer having an average particle diameter of 0.2 to 50 .mu.m and hot toluene insolubles content of 30 to 95% by weight.
