A flame retardant finishing is given to inflammable thermoplasts, such as linear polyesters and polyamides, by intensely mixing the granular thermoplasts with red phosphorus and a mono-, di-, or tri-ester of orthophosphoric acid until the granules are provided with a flame retardant coating. Suitable esters are those with high molecular weight aliphatic alcohols and phenols or their ethoxylation products. |
