Haloalkylsulphonylarenes and aryl haloalkanesulphonates as fire retardant additives

摘要

A sulphone or sulphonate of the general formula: A-SO2-(O)x-Ar, wherein x = 0 (sulphone) or 1 (sulphonate); Ar is an aryl group, e.g. Ph; and A is a C2-20 alkyl group bearing at least one halo-substituent, e.g. chloro-octyl, may be used as a fire-retardant additive for organic polymers and particularly as a fire-retardant primary plasticiser for chlorine-containing polymers, e.g. PVC.
