STABILIZED POLYESTERS AND POLYESTER URETHANES CONTAINING AN AROMATIC CARBODIIMIDE AND A QUINONE |
| 摘要 |
Polyesters and polyester urethanes are stabilized against discoloration and hydrolytic degradation by inclusion therein of an aromatic carbodiimide and either a benzohydroquinone or a naphthohydroquinone compound, and at the same time, the quantity of isocyanate eliminated from polyester urethanes is considerably reduced.
