Abstract
Abstract Compounds of the formula: IN WHICH R1 and R2 are alkyl groups; R3 is -H or an alkyl group; and R4 is -H, -Cl or an alkyl group ARE PRODUCED BY ACYLATING A DIALKYL ACYL PHOSPHONATE UNDER CONDITIONS OF EITHER ACID OR BASE CATALYSIS WITH AN ALKANOIC ACIE ANHYDRIDE, HALIDE OR A MIXTURE THEREOF. The dialkyl 1alkanoyloxy-alk-1-enyl-phosphonates of this invention are useful as flame retarding agents for textile materials and in the production of polymers and copolymers which possess flame retardant properties.
