DEFINITION

Classification: 264/331.15

Ethylenically unsaturated polymer or polymer derived from ethylenically unsaturated monomer:

(under subclass 331.11) Processes in which the synthetic resin is an ethylenically unsaturated polymer or a polymer derived from an ethylenically unsaturated monomer.

(1) Note. Ethylenically unsaturated requires the presence of 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 of a double bond with an aromatic ring.
