FIELD: polymer materials. SUBSTANCE: invention makes it possible to optimize bitumen/polymer mixture intended, in particular, for manufacturing hermetic diaphragms. Percentage of a variety of polymers such as atactic polypropylene, isotactic polypropylene, ethylene/propylene-type mixtures in bitumen/polymer mixture is determined from at least one physical characteristic of mixture using method described in the book J. Goupy "La methode des plans d'experiences", Dunod, pp 9-82. Invention also covers a method for preparing bitumen/polymer mixture with specified physical characteristics and a method for modifying this mixture. EFFECT: facilitated preparing bitumen/polymer mixture with desired characteristics. 10 cl |
