KINETICS, MECHANISMS, AND SYNTHESIS STUDIES OF RING-OPENING-CLOSING ALTERNATING COPOLYMERIZATION
The present paper describes the ring-opening-closing alternating copolymerization of cyclic phosphonites (2-phenyl-1,3,2-dioxaphospholane (1a), 2-phenyl-1,3,2-dioxaphosphorinane(1b), 2-phenyl-1,3,2-dioxaphosphepane(1c), and 2-phenyl-4H-1,3,2-benzodioxa phosphorin-4-one(1d) with muconic acid(2a), succinaldehyde(2b), glutaraldehyde(2c), adipinaldehyde(2d), o-phthalaldehyde(2e), acrylic anhydride(2f), methacrylic anhydride(2g), N-methyl diacrylamide(2h), and N-methyldimethacrylamide(2i). The reaction of a 1:1 monomer feed ratio, explained by a mechanism of propagation via zwitterion intermediates, proceeds without any added catalyst to give an alternating copolymer 3 involving ring-opening of 1 and ring-closing of 2. The structure of copolymer 3 was determined by H-1, C-13 NMR, P-31 NMR and IR spectroscopies as well as elemental analysis.
