Patent

CA 2010319

A foamable polymer compositor comprising [A] at least one cyclo-olefin resin selected from the group consisting of (A-1) ring-opened polymers derived from cyclo-olefins represented by the following general formula [I], (A-2) ring-opened copolymers derived from the cyclo-olefins of general formula [I], (A-3) hydrogenation products of the ring-opened polymers (A-1), (A-4) hydrogenation products of the ring-opened copolyers (A-2), and (A-5) addition polymers of the cycloolefins of general formula [I] with ethylene, and (B) a blowing agent, Image 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 polycyclic hydrocarbon group; and R9 and R10, or R11 and R12 may each form an alkylidene group.
