STUDIES ON COPOLYCONDENSATION MECHANISMS FROM m-METHOXY-p-ACETOXYBENZOIC ACID,p-ACETOXYBENZOIC ACID AND POLY(ETHYLENE TEREPHTHALATE)
Copolycondensation mechanisms for the terpolyester system from m-methoxy-p-acetoxybenzoic acid,p-acetoxybenzoic acid and poly(ethylene terephthalate)are first investigatedby high resolution proton NMR spectroscopy at 400 MHz.A series of reactivity ratios of thecopolycondensation reactions are given.The results shown that the m-methoxy-p-acetoxybenzoicacid tends to homopolymerize,while the p-acetoxybenzoic acid,and the ethylene terephthalate unitespecially,tend to copolymerize with the m-methoxy-p-acetoxybenzoic acid.
