Abstract

The synthesis of non linear block copolymers of the type (BA)2B (3-miktoarm star copolymer), (BA)3B (4-miktoarm star copolymer), (BA)3B(AB)3 (super H-shaped), B2AB2 (H-shaped) and (B,A)A(B,A) (π-shaped), where A is polyisoprene 1,4 and B is polystyrene was performed using anionic polymerization techniques and suitable chlorosilane chemistry. Characterization data showed that the samples are molecularly and compositionally homogeneous. TEM, SAXS and SANS were used to study the microphase behavior of the copolymers. For all samples, the results were analyzed in the frame of the theoretical predictions given by Milner and taking into account the results from previous studies on the A2B and A3B miktoarm star copolymers.
