DEFINITION

Classification: 525/444.5

Solid polymer derived from or system contains a reactant which is a fatty acid glycerol ester, a fatty acid or salt derived from a naturally occurring glyceride, tall oil, or fatty acid derived from tall oil:

(under subclass 444) Subject matter wherein (a) a solid polymer is derived from a reactant which is a fatty acid glycerol ester, a fatty acid or salt thereof derived from a naturally occurring glyceride, tall oil, or fatty acid derived from tall oil; or (b) wherein the system contains a reactant noted in (a) above as a separate reactant or as an additional reactant with the polycarboxylic acid derivative and polyhydroxy reactant or polymer thereof.
