The invention provides blends comprising an ethylene copolymer formed from ethylene with at least one comonomer selected from (a) the group comprising compounds represented by the formula H.sub.2C.dbd.CHR wherein R represents a C.sub.1-C.sub.20 linear, branched or cyclic alkyl group or a C.sub.6-C.sub.20 aryl group, and (b) a C.sub.4-C.sub.20 linear, branched or cyclic diene. Each copolymer has a specific density, a specific molecular weight distribution, and a specific comonomer content distribution characteristic.
