DEFINITION

Classification: 264/331.13

Polymer derived from monomer having at least two ethylenic groups (e.g., ABS rubber, chloroprene, etc.) or with natural rubber:

(under subclass 331.11) Processes wherein the synthetic resin is a polymer derived from a monomer having at least two ethylenic groups, e.g., ABS rubber, chloroprene, etc., or wherein the organic material comprises a synthetic resin with

a natural rubber.

(1) Note. An ethylenic group is defined as two carbon atoms bonded together by a double or triple bond, with the proviso that the double bond is not part of an aromatic ring, or of a ring which shares a double bond with an aromatic ring.
