Abstract
AbstractTracer diffusion coefficients D* of both components were measured in mixtures of polystyrene with poly(o‐methylstyrene), poly(p‐methylstyrene), and a commercially available random copolymer of p‐ and m‐methylstyrene, respectively. D* values were determined by applying the holographic grating technique where between 5 and 10% of the respective polymer component was labelled at the end group with a photoreactive dye. For molecular weights between 15 000 and 37 000 and temperatures between 175 and 200°C, the D* values differed relatively slightly when compared at equal molecular weight and equal temperature distance T–Tg from the glass transition temperature Tg. The differences were compared with those of monomeric friction coefficients obtained from dynamic mechanical experiments.
