DEFINITION

Classification: 525/167.5

With a reactant which is a fatty acid glycerol ester, a fatty acid or salt derived from a naturally occurring glyceride, tall oil, or a fatty acid derived from tall oil:

(under subclass 165) Subject matter wherein there is at least one reactant which is a fatty acid glycerol ester, or a fatty acid or salt thereof derived from a naturally occurring glyceride, tall oil, or a fatty acid derived from tall oil.

(1) Note. The recited fatty material is reacted with the

solid polymer derived from ethylenic reactants only; or with the polycarboxylic acid or derivative or polyol, or with the condensate or solid polymer thereof.
