Abstract of the Disclosure A thermoplastic resin composition composed of [A] 5 to 90 % by weight of a linear polyolefin having an intrinsic viscosity [µ], measured in decalin at 135 °C, of l.0 to 15.0 and a crystallinity of at least 45 % and formed substantially of from 8 to 40 % of an ultrahigh-molecular-weight polyolefin having an intrinsic viscosity [µ], determined at 135 °C, of 10 to 40 dl/g and 60 to 92 % of a low-molecular-weight to high-molecular- weight polyolefin having an intrinsic viscosity [µ], measured in decalin at 135 °C, of 0.1 to 5.0 dl/g, and [B] 95 to 10 % by weight of at least one type of cyclo-olefin resin having an intrinsic viscosity, measured in decalin at 135 °C, of 0.05 to 10 dl/g and a softening temperature of at least 70 °C and selected from ring-opened polymers and ring-opened copolymers derived from cyclo-olefins represented by the following formula [I], Image [I] wherein n is 0 or a positive integer, R1 to R12, independently from each other, represent an atom or a group selected from the class consisting of a hydrogen atom, halogen atoms and hydrocarbon groups, R9 to R12 may be linked to each other to form a monocyclic or poly- cyclic group which may have a double bond, and R9 and R11, or R10 and R12, may each form an alkylidene group. hydrogenated products of said polymers or copolymers, and addition polymers of ethylene with the cyclo-olefins of formula [I]. The composition is suitable for obtaining molded articles having self-lubricating property, molding dimensional stability, heat resistance and rigidity in a well-balanced combination.
