Document Type and Number:
Japanese Patent JPH11514680
Kind Code:
A
Abstract:
The present invention relates to foams comprising cycloolefin copolymers. The foam of the invention comprises at least one cycloolefin copolymer which comprisesfrom 0.1 to 100% by weight, based on the total mass of the cycloolefin copolymer, of polymerized units derived from one or more polycyclic olefins having one or more norbornene units andfrom 0 to 99% by weight, based on the total mass of the cycloolefin copolymer, of polymerized units derived from one or more acyclic olefins of the formula where Ri, Rii, Riii and Riv are identical or different and are each a hydrogen atom, a linear, branched, saturated or unsaturated C1-C20-hydrocarbon radical or a C6-C18-aryl radical andfrom 0 to 99% by weight, based on the total mass of the cycloolefin copolymer, of polymerized units of one or more monocyclic olefins of the formula VIII where n is a number from 2 to 10, and voids which can contain one or more gaseous substances.
