Zusammenfassung:	PURPOSE:To provide the titled composition having excellent heat deformation resistance and high stability to heat and light, by compounding a vinyl chloride polymer with a hydrogenated product of a ring-opened polymer of 5-cyanobicyclo [2.2.1]heptene-2. CONSTITUTION:The objective composition is produced by compounding (A) 70-5wt% vinyl chloride polymer with (B) 30-95wt% polymer obtained by the hydrogenation reaction of a ring-opened polymer of 5-cyanobicyclo[2.2.1]heptene- 2 to a hydrogenation ratio of >=50%. The component B can be produced by hydrogenating a polymer obtained by the ring-opening polymerization of a monomer of formula (R is H, 1-5C alkyl or cyano) or a mixture composed mainly of the monomer and containing other norbornene derivative or cycloalkene, by a process for the polymerization of a cyclic olefin.
