Salts of 1-hydroxydihydrophosphole oxides and 1-hydroxyphospholane oxides and use thereof as flame retardants. The salts of 1-hydroxydihydrophosphole oxides and 1-hydroxyphospholane oxides are useful as flame retardants, especially for plastics such as polyester or polyamide. The aluminum salts are preferred.

1-hydroxydihydrophosphole oxides and 1-hydroxy-phospholane oxides,

Polyesters such as polyethylene terephthalate or polybutylene terephthalate are provided with a flame-retardant finish by addition of calcium salts or aluminum salts of phosphinic or diphosphinic acids.

Flameproofed polyester molding compositions

Salts of phosphonous acids are useful as flame retardants in plastics. Preferred salts are calcium or aluminum salts of phenylphosphonous acid and of methanephosphonous acid. Plastic molding materials rendered flame-retardant in this way are useful for manufacturing molded parts, especially electrical components, mechanical components, plugs, mounts, housings, coverings, sheathings and overcoatings.

Flameproofed polyester molding composition

Low-flammability polyamide molding materials are obtained by admixing calcium or aluminum phosphinates. These salts confer improved flame protection on polyamides compared with other metal salts.
