Salen Copper Complexes: A Novel Flame Retardantfor Thermoplastic Polyurethane

摘要

Herein we present the synthesis and the use of salen copper complexes as flame retardants in TPU. Fire retardancy evaluated by mass loss calorimeter show that 10% loading in TPU decreases significantly the peak rate of heat released (pRHR). The diminution of pRHR depends of the structure of the salen copper complex. The first investigations of mechanism suggest condensed phase action.
