Abstract
A random copolymer comprising ethylene, an .alpha.-olefin and a branched conjugated polyvalent olefin, wherein (i) ethylene, the .alpha.-olefin and an iodine value respectively satisfy the following inequalities: 0<ethylene<100 (% by mol), 0<.alpha.-olefin<100 (% by mol) and 0<iodine value<370 (g/100 g), (ii) an intrinsic viscosity [.eta.] measured in decalin at 135.degree. C. of the random copolymer satisfies the following inequality: 0.1 (dl/g)<[.eta.]<10 (dl/g) and (iii) a molecular weight distribution (Mw/Mn).ltoreq.5.
