The determination of monomer sequence distributions in polymer backbones, and the variation of these distributions to optimize polymer properties, is the focus of considerable industrial research activity. Details of copolymer molecular structure as a function of method of synthesis and processing history have been elucidated using a variety of combined approaches. A controlled sequence polyester has been synthesized through the interfacial polymerization of di(p-chlorocarbonylphenyl) isopthalate with the disodium salt of hydroquinone. Infrared bands related to the C-O motion have been calibrated against known structural parameters as determined by NMR analysis. The infrared method extended the range of samples that could be analyzed since a minimal amount of sample was required and the diad distributions could be determined for insoluble materials.
