N-Methacryloyloxyphthalimide (NMPI) and N-methacryloyloxytetrabromophthalimide (NMTPI) were prepared by the reaction of methacrylic acid with N-hydroxyphthalimide and N-hydroxytetrabromophthalimide, respectively. The resulting monomers were polymerized. The reactions of the resulting polymers with hydroxy and amine compounds have been studied. ZUSAMMENFASSUNG:N-Methacryloyloxyphthalimid und N-Methacryloyloxytetrabromphthalimid wurden durch Reaktion von Methacrylsaure bzw. Methacryloylchlorid mit N-Hydroxyphthalimid bzw. N-Hydroxytetrabromphthalimid hergestellt und homopolymerisiert. Die Austauschreaktionen der Polymeren mit Hydroxy-und Amin-Verbindungen wurden untersucht.

SynopsisThe monomer reactivity ratios for the copolymerization of triphenyltin methacrylate with methyl acrylate, ethyl acrylate, and butyl acrylate have been found to be rl = 2.58, r2 = 0.66, rl = 2.37, r2 = 0.43, and rl = 1.27, r2 = 0.39, respectively. Also, the copolymerization parameters of triphenyltin methacrylate with methyl methacrylate and butyl methacrylate were as follows: rl = 0.94, r2 = 0.99, and rl = 0.68, r2 = 0.83, respectively. Copolymerization reactions were carried out in solution at 70°C using 1 mol % AIBN, and the copolymer compositions were determined by tin analysis. The sequence distribution of the alternating diad fractions for the systems studied were calculated at various feed compositions. The structure of the triphenyltin methacrylate monomer as well as its azeotropic copolymer with butyl methacrylate were investigated by IR spectroscopy.

The synthesis of N‐acryloyloxy‐ and N‐methacryloyloxyphthalimides were accomplished in fair yield by reaction of acryloyl and methacryloyl chlorides with N‐hydroxyphthalimide in the presence of triethylamine. The resulting monomers were polymerized. The ability of the prepared activated polymers to enter exchange reactions with hydroxylated compounds and amines was tested.

SynopsisThe monomer reactivity ratios for the copolymerization of tributyltin acrylate with styrene and allyl methacrylate have been found to be rl = 0.213, r2 = 1.910 and rl = 0.195, r2 = 2.257, respectively. Also, the copolymerization parameters of tributyltin methacrylate with styrene and allyl methacrylate were as follows: rl = 0.256, r2 = 1.104 and rl = 2.306, r2 = 1.013. Copolymerization reactions were carried out in solution at 7OoC using 1 mole % AIBN, and the copolymer compositions were determined by tin analysis. Ternary copolymerization of the three systems butyl methacrylate-tributyltin methacrylate-acrylonitrile, butyl acrylate-tributyltin methacrylate-acrylonitrile, and styrenetributyltin acrylate-acrylonitrile have been studied, and the terpolymer composition of each system was determined through tin and nitrogen analyses. The variation of instantaneous and average terpolymer composition with conversion fit satisfactorily the experimental results over a wide range of conversion.
