DEFINITION

Classification: 525/111.5

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 107) Subject matter wherein there is, in addition, 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 contacting of the polymer with the fatty acid material can be prior, concurrent, or subsequent to contacting with the poly 1, 2-epoxide material.
