Notes:
The sequence distribution of liquid-crystalline poly(ethylene terephthalate-co-oxybenzoate)s was determined by 13C NMR spectroscopical investigations of samples with different compositions. All possible oxybenzoate- and terephthalate-centered triads could be identified and assigned. The analysis of NMR substituent effects confirms the assignment. The comparison of the calculated statistical with the experimentally determined triad distribution shows a tendency for the formation of oxybenzoate blocks in the polymer chain.
