A method for determining the mixing ratio of polymers comprises (A) adding separate tracer compds. having different compsns. to the employed polymer, (B) mixing and vulcanizing, (C) treating vulcanized polymer samples under its particles producing condns., (D) extractine an analytical amts. of separate tracer compds. by solvent system in sufficient time, (E) separating solvent from polymer particles and (G) determing the mixing ratio of polymers from (F) data.
