ABSTRACT:
Modified polytetramethylene ether glycol containing a 2,3-dibromo-2-butene segment is disclosed. This glycol maintains or improves properties of flexible polyurethanes and polyesters made therefrom and, in addition, improves the fire retardant properties of these resulting polymers. The chemically stable fire retardant diol provides a reactive flame retardant which is non-fugitive and non-migratory, and is neither extracted, nor volatilized from the elastomer into which it is incorporated.
