Abstract

Purpose ‐ To 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/approach ‐ Preparation 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. Findings ‐ NATP 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/implications ‐ The 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 implications ‐ The 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/value ‐ The method of preparation of organotin polymers was novel and may be useful for preparation of other organotin polymers and copolymers.
