DEFINITION

Classification: 526/283

(under subclass 281) Subject matter wherein the bridged ring monomer is a dicyclopentadiene containing moiety.

(1) Note. This subclass includes dicyclopentadiene, per se, as well as derivatives of dicyclopentadiene having at least the basic structure of dicyclopentadiene, shown below, available ethylenic bonds but wherein the hydrogen atoms of dicyclopentadiene may have been substituted by other atoms.
