DEFINITION

Classification: 524/573

Interpolymer of two or more diene monomers:

(under subclass 571) Subject matter wherein a -C=C-C=C-hydrocarbon monomer has been interpolymerized with at least one hydrocarbon containing at least two ethylenic groups.

(1) Note. The hydrocarbon containing at least two ethylenic groups may be a conjugated or nonconjugated diene.
