| titleOfInvention | Catalysing the replacement of aromatic nuclear halogen by sulphur,and polymers produced thereby |
| abstract | Polyphenylene sulphides are prepared by reacting at least one compound having an aromatic nucleus substituted by chlorine, bromine or iodine with sulphur in the presence of a carboxylic acid derivative having a chlorine, bromine or iodine atom directly attached to a nitrogen atom which is directly attached to at least one acyl group and an alkali metal or alkaline earth metal oxide, carbonate or sulphide. The aromatic compound is suitably a halobenzene or a halo-phenyl substituted triazine and the reaction mixture preferably contains at least one tri-halogen substituted compound to effect cross-linking in the product. Suitable carboxylic acid derivatives are N-chlorosuccinimide, N - bromosuccinimide, N - iodosuccinimide, N-bromophthalimide, N-bromocaprolactam, N - bromacetamide and isocyanuric bromide. |
