Flame-retardant phosphorus-functional polyether carbonate polyol and method for production thereof

Abstract

A process for preparing a phosphorus-functional polyethercarbonate polyol, comprising reacting a polyethercarbonate polyol having unsaturated groups with a phosphorus-functional compound of formula (Ia): wherein X=O or S; and wherein R1 and R2 are selected from the group consisting of C1-C22 alkyl, C1-C22 alkoxy, C1-C22 alkylsulfanyl, C6-C70 aryl, C6-C70 aryloxy, C6-C70 arylsulfanyl, C7-C70 aralkyl, C7-C70 aralkyloxy, C7-C70 aralkylsulfanyl, C7-C70 alkylaryl, C7-C70 alkylaryloxy, C7-C70 alkylarylsulfanyl, or wherein R1 and R2 are bridged to one another directly and/or via heteroatoms and are selected from the group consisting of C1-C22 alkylene, oxygen, sulfur, and NR5, wherein R5 is hydrogen, C1-C22 alkyl, C1-C22 acyl, C7-C22 aralkyl, or C6-C70 aryl radical. A process for preparing a phosphorus-functional polyurethane polymer is disclosed. Phosphorus-functional polyethercarbonate polyol, phosphorus-functional polyurethane polymer, flame-retardant adhesion promoter, filler-activator, flame retardant, flame-retardant coating, foam, sealing compound, thermoplastic, thermoset, rubber, and a moulded body are disclosed.
