Abstract

Anionically synthesized poly(p-t-butylstyrene)-b-poly(dimethylsiloxane)-b-poly(p-t-butylstyrene) block copolymers containing about 28% by weight p-t-butylstyrene were characterized by using differential refractometry, light scattering and viscosity methods in a good solvent, benzene, and in a selective solvent, methyl ethyl ketone. The unperturbed chain dimensions were estimated. Results were discussed with regard to the conformation of block copolymers in solution. © 1990.
