Preparation of new organotin polymers via exchange reactions

Preparation of new organotin polymers via exchange reactions Purpose – Preparation of new organotin polymers via a new synthetic route based on the exchange reactions of pentachlorophenyl acrylate or methacrylate with amino‐tri‐phenyltin benzoates or hydroxyl‐tri‐phenyltin benzoates. Design/methodology/approach – The pentachlorophenyl acrylate or methacrylate was prepared by polymerisation in solution with azobisisobutyrontrile as a free radical initiator. The polymers obtained were allowed to undergo exchange reactions with amino‐tri‐phenyltin benzoates or hydroxyl‐tri‐phenyltin benzoates. The structure of the polymers prepared was confirmed by IR spectroscopy. Films were prepared from purified organotin polymers solution on glass, PVC and tin plates. The release of tin compound from the films, when immersed in aqueous media, was assessed. The concentration of the released tin (ppm) was measured by atomic adsorption spectrophotometer. Findings – The new synthetic route was effective, the organotin polymers prepared had good film properties and the release of tin compounds increased with the content of tin in the organotin polymers. Research limitations/implications – The alkaline resistance of the polymeric films prepared needs improvement. Practical implications – The polymers prepared provide a family of effective polymeric fungicide useful for a number of applications including water sterilisation. Originality/value – The polymers prepared contained pendent triphenyltin moieties which slowly hydrolysed to give fungicidal and antifouling effects. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Pigment & Resin Technology Emerald Publishing

Abstract

Purpose – Preparation of new organotin polymers via a new synthetic route based on the exchange reactions of pentachlorophenyl acrylate or methacrylate with amino‐tri‐phenyltin benzoates or hydroxyl‐tri‐phenyltin benzoates. Design/methodology/approach – The pentachlorophenyl acrylate or methacrylate was prepared by polymerisation in solution with azobisisobutyrontrile as a free radical initiator. The polymers obtained were allowed to undergo exchange reactions with amino‐tri‐phenyltin benzoates or hydroxyl‐tri‐phenyltin benzoates. The structure of the polymers prepared was confirmed by IR spectroscopy. Films were prepared from purified organotin polymers solution on glass, PVC and tin plates. The release of tin compound from the films, when immersed in aqueous media, was assessed. The concentration of the released tin (ppm) was measured by atomic adsorption spectrophotometer. Findings – The new synthetic route was effective, the organotin polymers prepared had good film properties and the release of tin compounds increased with the content of tin in the organotin polymers. Research limitations/implications – The alkaline resistance of the polymeric films prepared needs improvement. Practical implications – The polymers prepared provide a family of effective polymeric fungicide useful for a number of applications including water sterilisation. Originality/value – The polymers prepared contained pendent triphenyltin moieties which slowly hydrolysed to give fungicidal and antifouling effects.
