FIELD: physico-chemical analysis in various branches of science, technology and industry. SUBSTANCE: method is employed where determination of degree of crystallinity of natural polymers is required. Signal of free induction is excited in specimens of different moisture content and times of spin-spin relaxation are found. Results of these measurement are used of compute degree of crystallinity by corresponding formula. EFFECT: simplicity and high accuracy of method. 1 dwg, 1 tbl
