Abstract
Abstract The invention relates to a vulcanized elastomer composition consisting essentially of a vulcanized mixture of (1) a macromolecular polymer compound selected from the group consisting of substantially amorphous polymers of bicyclo (2.2.1) heptene-2 and its substituted derivatives (2) at least one compound having a low volatility and a freezing point less than -30* C, this mixture of said polymer and said low volatility compound prior to vulcanization having a glass transition temperature lower than about -10* C, said vulcanized composition having a combination of good mechanical and physical properties.
