DEFINITION

Classification: 585/17

Polymer of indefinite molecular weight:

(under subclass 16) Subject matter wherein the product is a molecule or mixture of molecules which cannot be defined by an empirical formula in which all numerical values are invariable, and which has been formed by the union of smaller entire hydrocarbon molecules (addition polymerization) or the hydrocarbyl moieties of nonhydrocarbon molecules (condensation polymerization).

(1) Note. The smaller (monomer) molecules may be all alike or two or more varieties may make up portions of the final product molecule.

(2) Note. Polymers included herein generally are waxy or liquids or can have a molecular weight less than is required for placement in Classes 520+. While "solid polymer" implies that a product is a resin for Classes 520+, the designation of the product as a "wax" makes it suitable for this class (585).
