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.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1975-50-4 is helpful to your research. Product Details of 1975-50-4.
