DEFINITION

Classification: 522/88

Processes involving carbohydrates as reactant or as solid polymer; or compositions therefore:

(under subclass 1) Subject matter involving the preparation of a carbohydrate containing solid polymer; or the chemical modification of a solid polymer derived from a carbohydrate; or the modification of a solid polymer by reaction with a carbohydrate; or composition therefore.

(1) Note. See Class 520 (a) the Glossary for a definition of the term "carbohydrate" and (b) Lines With Other Classes and Within This Class, section E for the type of polymer containing a carbohydrate that qualifies as a synthetic resin under the Class 520 Series.
