Interaction between non-identical polymer molecules in a dilute solution of a mixture of two polymers is quantitativel) characterized by the interaction parameter A>t which is the second xirial coefficient for interaction of unlike species.

A~tract--The solution behaviour of four dextran fractions with molar masses between 2.3 x 105 and 13 Γ 10 ~' g/mol in water was investigated by dynamic light scattering in the region 25-120cC and 1 2000 bar. It has been pointed out that the diffusion coefficient increases with temperature (as a cons
