Abstract
The bulk melt polycondensation of 2,6-acetoxynaphthoic acid [poly (2,6-oxynaphthoate) (P-ON)] at temperatures below 250°C made it possible to prepare P-ON samples with phase II content approaching 100%. The structure, morphology, and melting behavior of P-ON phase II are described and compared with a similar liquid crystal polyester, poly (p-oxybenzoate).
