NOVELTY - A resin solution contains a norbornene group ring-opened-polymer hydride and an organic solvent. The norbornene group ring-opened-polymer hydride is obtained by hydrogenating 80% or more of carbon-carbon double bond of ring-opened-polymer produced by ring-opening polymerization of monomer mixture containing 2-norbornene or 2-norbornene and a substituent containing norbornene group monomer. The polymer comprises repeating unit (A) (in wt.%) (90-100) derived from 2-norbornene and repeating unit (B) (0-10) derived from substituent containing norbornene group monomer.    USE - Resin solution is used for molded product (claimed). Can also be used as coating material of building materials such as timber, steel frame, wall paper and roof, industrial components such as industrial machines, electronic device, bolt, nut, spring and piping, precision equipments such as personal computer, mobile telephone, household appliance and information recording medium, packaging/conveyance containers or films of semiconductor components, foodstuff, medical devices and health care products, energy related components such as fuel cell and solar cell, and movable components such as motor vehicles, electric trains, vessels, airplane and rocket.    ADVANTAGE - The resin solution provides molded product having excellent flexibility, oil resistance and damp-proof property.    DETAILED DESCRIPTION - A resin solution contains a norbornene group ring-opened-polymer hydride having melting point of 110-145 degrees C and an organic solvent. The norbornene group ring-opened-polymer hydride is obtained by hydrogenating 80% or more of carbon-carbon double bond of a ring-opened-polymer produced by ring-opening polymerization of monomer mixture containing 2-norbornene or 2-norbornene and a substituent containing norbornene group monomer. The polymer comprises a repeating unit (A) (in wt.%) (90-100) derived from 2-norbornene and a repeating unit (B) (0-10) derived from substituent containing norbornene group monomer.
