(57) [Summary] A crosslinked product of a syndiotactic propylene copolymer having an excellent balance of heat resistance, abrasion resistance and flexibility. To provide a thermoplastic resin composition containing the crosslinked product and a molded article thereof. A crosslinked product of a syndiotactic propylene copolymer comprises: (a) a propylene unit; and (b) an olefin unit having 2 to 20 carbon atoms other than propylene. (C) a polyene unit, and (a) a unit of 99 to 5 0 mol%, comprising (b) units in an amount of 1 to 50 mol%, (A) The unit (c) is contained in an amount of 0.01 to 30 mol% with respect to 100 mol% of the total amount of the units (b) and In addition, the syndiotactic propylene copolymer in which the chain of the unit (a) has a substantially syndiotactic structure is crosslinked. The thermoplastic resin composition comprises a crosslinked product of the syndiotactic propylene copolymer and a thermoplastic resin. |
