Abstract
Glass-reinforced polyglutarimides exhibit improved impact resistance when low levels of phenoxy resin are incorporated into the blend.
Claims14
A blend comprising:
- a. From about 80 to about 99.5 parts, based on total polymer content, of a polyglutarimide;
- b. From about 0.5 to about 20 parts, based on total polymer content, of a phenoxy resin;
- c. From about 10 to about 50 parts, based on the total weight of all components of the blend, of an inorganic fiber or particulate with functional surface groups.
