Glutaric anhydride is a carboxylic acid anhydride used as an intermediate
| [Definition]
ChEBI: Glutaric anhydride is a cyclic dicarboxylic anhydride that is oxane which carries oxo groups at positions 2 and 6. It is used as an intermediate in the production of pharmaceuticals, corrosion inhibitors, and polymers (E.g. epoxy polyesters). It is a cyclic dicarboxylic anhydride and a member of oxanes. It is functionally related to a glutaric acid. | [Polymerization]
Thermoplastic copolymers of glutaric anhydride and (meth)acrylic esters are prepared free of acid groups by reacting a (meth)acrylic ester polymer with a secondary amine at from 150° to 400°C. Where the secondary amine is sufficiently volatile, any excess is removed at above 160°C and below 26.6 kPA. The copolymers are amorphous, soluble, non-crosslinked and low acid. They may be blended with other polymers, formed into plastic articles, or swelled with cross-linking agents. |
