METHOD OF PREPARING SOLUTION OF POLYMERS BASED ON NATURAL AND/OR SYNTHETIC RUBBER Russian patent published in 2003 - IPC

FIELD: polymer materials. SUBSTANCE: invention is dealing with adhesion polymer compositions containing 15-25% natural and/or synthetic rubber with average molecular weight above 20000 and high degree of crystallinity. Method involves mixing of crude solid polymer and, if necessary, auxiliary substances and various additives with organic solvent or solvent mixture. Further, mixture is vigorously stirred in turbulent mode at needed Reynolds criterion and during a period of time long enough to destroy polymer and completely dissolve it thereby forming homogenous mass. Auxiliary substances and various additives can possibly be added during stirring. EFFECT: simplified technology, reduced process time, reduced power and materials consumption, and improved environmental condition. 2 cl, 1 tbl, 8 ex
