DEFINITION

Classification: 585/507

More than two double bonds, e.g., diene polymerization, etc.:

(under subclass 506) Subject matter wherein the product has three or more ethylenically unsaturated sites in its molecule.

(1) Note. An addition product is presumed to have three or more double bonds when all the monomer molecules have two or more double bonds.

(2) Note. The products of processes of this subclass are often of utility as synthetic drying oils.
