| Abstract: | Determination of molecular weights of polymers by 1H-NMR spectroscopy is discussed. A brief survey of application of NMR; both 1H and 14C, in the analysis of monomer sequence, copolymer composition, polymer microstructure, end-group and relaxation phenomenon is also made. NMR offers an elegant and simple yet fairly accurate method for determination of molecular weights of polymers. |
