Copolymer,effective in the study of vinyl copolymers and reveals the structural and sequence details that cannot be detected by any other means. Copolymer composition can be determined very easily by NMR, particularly by .H NMR, and the method is usually more accurate than other traditional analytical methods, such as elemental analysis.

0945-6074 roscopy of Polymers places emphasis on the practical use of NMR spectroscopy in polymer chemistry rather than the theoretical treatments. Based on the authors‘ extensive experimental experience, topics covered include (1) experimental problems such as preparation of sample solution, selection of sol

NMR for the Study of Polymerization Reactions, termination reactions, combination and disproportionation, as far as chain-transfer reactions are negligible. When a polymer molecule is formed through combination, the chain contains two initiator fragments on both ends, while that formed through disproportionation contains one fragment (Structure 5.1).

NMR Relaxation,ameters besides chemical shifts and spin-coupling constants. In this chapter the basic principles of NMR relaxation and its practical application to polymers are described. A detailed description of NMR relaxation and its application for general purposes are found in Refs. .
