DEFINITION

Classification: 525/332.1

Monomer contains non-conjugated diene group, or at least one fused or bridged ring or at least one cycloaliphatic structure:

(under subclass 331.9) Product wherein said diene monomer contains nonconjugated ethylenic groups, or wherein at least one monomer contains a fused or bridged ring or a cycloaliphatic structure.

(1) Note. Nonconjugated ethylenic groups denotes monomers wherein two or more ethylenically unsaturated groups are (a) separated from each other either by an aromatic ring (e.g., divinyl benzene) or (b) separated by at least one carbon atom of an acyclic carbon chain which carbon atom is not part of a methine group, e.g., -C=C-C-C=C-, etc;, or (c) wherein two ethylenically unsaturated groups share a single carbon atom, etc., C=C=C

(2) Note. Included herein are monomers containing ethylene groups which are both conjugated an nonconjugated, e.g., myrcene: [figure]
