Notizen:
PMR spectroscopy and lanthanide shift reagents were used to determine sequence distribution of units of poly(dimethyldian-phenolphtalein)terephthalate. The calculated values of degree of randomness confirm the theory that the copolyester obtained at the isokinetic temperature (200°C) has random distribution of comonomer units and copolyesters obtained at temperatures above and below this temperature have a tendency to form block units along the macromolecular chain.
