Self-assembled structures in d8-polystyreneblock- polyisoprene/polystyrene blends in the weak segregation regime: SAXS and TEM study

Original language description

This paper reports an investigation of the microphase-separated morphology in blends of d-PS ?PI with homo-PS in the weak segregation regime. The parameter rM = MH/MC (where MH and MC are the weight-average molecular weights of the homopolymer and corresponding block copolymer chain) was selected to encompass all possible types of mutual homopolymer/block copolymer sizes. The PS block chains behave as a wet brush for rM < 1 The domain spacing D increases systematically with increasing concentration of homopolymer wP and increasing rM regardless of the implemented specific morphology, but the slope of the periodicity D versus wP relation is smaller than in the intermediate and strong segregation regimes. The parameters rM and 3/2N (where is the Flory-Huggins parameter and N the number of segments per chain) characterize the slope of the D versus wP relation in the weak and intermediate segregation regimes.
