Synthesis and characterisation of organotin phthalimide polymers

Abstract

PurposeTo prepare and characterise organotin polymers via a new synthetic route by exchange reactions of poly‐N‐acryloyloxy‐ and poly‐N‐methacryloyloxy‐tetrabromophthalimide with hydroxy‐ and aminotri‐n‐butyltin benzoates.Design/methodology/approachPreparation of N‐acryloyloxytetrabromophthalimide (NATP) and N‐methacryloyloxytetrabromophthalimide (NMTP) by the reaction of N‐hydroxytetrabromo‐phthalimide with acryloyl or methacryloyl chloride. The exchange reactions of the resulting polymers with amino and hydroxytri‐n‐butyltin benzoate were carried out. The structure of the resulting compounds was characterised.FindingsNATP and NMTP were prepared by the reaction of N‐hydroxy‐tetrabromophthalimide with acryloyl or methacryloyl chloride in the presence of TEA. The monomers prepared were easily polymerised. The exchange reactions of poly‐NATP and poly‐NMTP with amino and hydroxytri‐n‐butyltin benzoate were studied. The structure of the polymers and copolymers prepared was confirmed by tin analysis, IR and 1HNR spectroscopy.Research limitations/implicationsThe new monomer described in the present investigation may be useful for the preparation of organotin polymers by a new synthetic route. Also, the organotin polymers prepared had good film properties and were suitable for film formation.Practical implicationsThe method for the preparation of monomer is simple and the exchange reactions provide a simple and practical solution for preparation of some classes of organotin polymers and copolymers.Originality/valueThe method of preparation of organotin polymers was novel and may be useful for preparation of other organotin polymers and copolymers.
