Polycyclic phosphate esters and process for preparing same

Polymeric halogenated organophosphorus diols are obtained by reacting chlorine or bromine with spirocyclic phosphites and thereafter reacting the halogenated product with a diol, in the presence of an acid acceptor. These novel viscous polymers react with polyisocyantes to produce polyurethanes. Polyurethanes so made are characterized by improved flame retardant properties compared with conventional polyurethanes. Such polyurethanes are preferably in the form of foams, especially flexible foams.

Flame retardant polyurethanes from polymeric halogenated organo

Polymeric bromine-containing phosphoramidate polyols are obtained by reacting bromine with spirocyclic phosphoramidites and thereafter reacting the brominated products with a polyol, in the presence of an acid acceptor. The novel viscous polymers thus produced react with polyisocyanates to produce polyurethanes. Polyurethanes so made are characterized by improved flame-retardant properties compared with conventional polyurethanes.
