ABSTRACT:
Mixtures of oligomeric phosphorus compounds which are obtained in the first step by reaction of a mono- to hexavalent alcohol with phosphinic, phosphonic and phosphoric acid derivatives containing at least one anhydride oxygen and possibly containing terminal acid P-OH radicals and by subsequent reaction in the second step with alkylene oxides or alkylene carbonates. These phosphorus compounds which contain hydroxyalkylphosphonic acid groups, may be suitably employed directly as flame-retardant finishes for textile articles or as intermediates thereof.
