Abstract
A polyolefinic resin which is a homopolymer of an olefin or a copolymer of olefins, has (i) intrinsic viscosity �.eta.! measured in decaline at the temperature of 135.degree. C. in the range of 0.5 to 10 deciliter/g and (ii) content of insoluble fraction in boiling n-heptane (W) in the range of 10 to 99 weight % and shows (iii) relation between relaxation time of rubber component measured by pulse NMR at the temperature of 30.degree. C. �T.sub.2H.sup.R (30):.mu.s!, relaxation time of rubber component measured by pulse NMR at the temperature of 80.degree. C. �T.sub.2H.sup.R (80):.mu.s! and the content of insoluble fraction in boiling n-heptane (W) satisfying the following equations:
