AbstractA general treatment is developed for the13C‐NMR analysis of polymers which contain several components. Reaction probability models and computer optimization techniques are used to resolve the NMR spectral data into separate components. The use of generalized multistate statistical models is introduced and is found to be very suitable for such systems. The computations are simplified by means of computer programs. The need for, and the relevance of, this approach are illustrated by the tacticity problems in polybutylene and polypropylene where two‐state and three‐state models are used, and copolymer triad sequence analysis for several olefin and acrylic copolymers where two‐state models are needed. Three copolymer examples are given: propylene/butylene, ethylene/propylene, and acrylamide/a
