PURPOSE:To make the subject processed product superior in mechanical strength and cutting processability and eliminate almost foul odor peculiar to the product, by a method wherein the product is constituted of an outer circumferential layer formed of a high-molecular material and a core body layer obtained by performing ring opening polymerization of a reactive stock solution containing a norbornene monomer of at least tricyclic body. CONSTITUTION:The inside of an outer circumferential layer 1 is replaced, for example, with inactive gas such as N2 by making use of the hollow outer circumferential layer 1 comprised of a high-molecular material such as rubber material as a mold. After heating of the outer circumferential layer 1 at a fixed temperature, a reactive stock solution containing a norbornene monomer prepared beforehand is supplied within the outer circumferential layer 1 through a supply pipe 16 by opening a three way valve 12. To improve adhesion between the outer circumferential layer 1 and core body layer 2 an adhesive layer constituted of a curing type adhesive agent is formed on an inner circumferential surface of the outer circumferential layer 1. Since the outer circumferential layer 1 is covered with the outside of the core body layer 2 comprised of a ring opening polymer of the norbornance monomer, the same hardly smell a foul odor peculiar to a polymer. Although the polymer constituting the core body layer 2 is light in weight, the molded product is superior in mechanical strength and moreover cutting properties. |
