DEFINITION

Classification: 523/414

Polymer contains more than one 1,2-epoxy group or one derived from reactant containing more than one 1,2-epoxy group is further derived from or reacted with organic nitrogen or sulfur compound:

(under subclass 402) Subject matter wherein the composition contains a polymer containing more than one 1,2-epoxy group or a polymer derived from a reactant containing more than one 1,2-epoxy group and is further derived from or reacted with an organic nitrogen or organic sulfur compound, e.g., a glycidyl polyether of bisphenol A cured with diethylene triamine, etc.
