Abstract
New antistatic compounds of formula ##STR1## WHEREIN R.sub.1 is alkyl optionally interrupted by 1 or 2 S, SO or SO.sub.2 moieties or 1 COO moiety, any alkyl(ene) being optionally hydroxyl-substituted; cycloalkyl; alkylcycloalkyl; or a mono- or polyoxyalkylene group terminated by alkyl, optionally alkyl-substituted phenyl or phenylalkyl:, PA1 n is 1 or 2; PA1 m is an integer 1 to 7; PA1 R.sub.2 is (m + 1) valent alkylene optionally interrupted by 1 or 2 O, S, SO or SO.sub.2 moieties; bivalent benzene, cyclohexane, biphenyl, diphenyloxide, -sulphide, -sulphoxide, -sulphone or -methane, 2,2-diphenylpropane, bis-cyclohexylmethane or 2,2-bis-cyclohexylpropane, or a (m + 1) valent mono- or polyoxyalkylene group containing R.sub.2 ; PA1 and each R.sub.3, independently, has one of the meanings given for R.sub.1, or is hydrogen or phenyl, naphthyl or phenylalkyl optionally substituted on the aromatic nucleus; a group ##STR2## having the above meanings; or a group ##STR3## in which R.sub.6 is alkyl, perfluoroalkyl or optionally substituted phenyl or naphthyl. Such compounds are useful as antistatic agents for organic materials, particularly a plastics material such as polypropylene, and may …
