ABSTRACT:
A set of tropodegradable bromine-containing hydrocarbon foam-blowing agents to (1) decrease the flammability of closed-cell foams and (2) to decrease flammability safety problems that may occur during foam production is disclosed. The agents are characterized by high flammability reduction efficiency and short atmospheric lifetimes. The latter property is essential and results in a low ozone depletion potential (ODP) and a low global warming potential (GWP). The agents are bromine-containing alkenes, bromine-containing ethers, bromine-containing amines, bromine-containing carbonyl compounds, bromine-containing aromatics, bromine-containing alcohols, and/or bromine-containing non-fluorinated alkanes.
