DEFINITION

Classification: 522/104

Processes involving an ethylenically unsaturated polyester derived from a polycarboxylic acid or derivative and polyol, condensate or solid polymer thereof; or compositions therefore:

(under subclass 1) Subject matter involving forming an unsaturated solid polymer from at least one polycarboxylic

acid or derivative and polyol or condensate thereof; or chemically modifying a solid polymer containing ethylenic unsaturation derived from at least one polycarboxylic acid or derivative and polyol or condensate thereof; or chemically modifying a solid polymer by treating with an unsaturated or saturated polycarboxylic acid or derivative and with a unsaturated or saturated polyol or codensate thereof with the proviso that at least the carboxylic acid or derivative, or polyol is unsaturated; or compositions therefore.

(1) Note. In the class definition, see section B in the General Summary of Subject Matter Within This Class for an explanation of the types of composition proper for this subclass.

(2) Note. The ethylenic unsaturation in the polymer need not be introduced by the polycarboxylic acid or derivative or polyol component, but can be in another reactant which is present during solid polymer formation.

(3) Note. The polycarboxylic acid or derivative and polyol need not be reacted with the solid polymer concurrently but may be added in a sequential manner.

(4) Note. See Class 520, Glossary, for a definition of the term "carboxylic acid or derivative".

(5) Note. A polyol contains two or more C-OH groups wherein the carbon atom bonded to the -OH moiety is not double bonded to a chalcogen atom.
