Triad concentrations obtained by 'H n.m.r, analysis enable the determination of the degree of randomness and average sequence length of poly(butylene terephthalate) (PBT) units for a number of melt processed PBT/polyarylate blends. Transesterification was confirmed by reduced degrees of crystallinity and melting points.
