Zusammenfassung:PURPOSE:A novel copolymer having each limited intrinsic viscosity, molecular weight distribution, and halogen content, improved compatibility with a solvent and various polymers, comprising an ethylenic component and an alpha-olefinic component in a specific ratio. CONSTITUTION:A low-molecular-weight ethylenic random copolymer comprising 30-75mol% ethylenic component and 25-70mol% alpha-olefinic component (e.g., propylene, 1-butene, 1-hexene, etc.), having 0.5-0.01dl/g intrinsic viscosity [eta]measured in decalin at 135 deg.C and
