Phase Behavior of Polystyrene-block-Poly(n-butyl -random-n-hexyl)methacrylate Copolymer |
| 초록 |
The phase behavior of polystyrene-block-poly(n-butyl-random-n-hexyl) methacrylate (PS-b-Pn(B-r-H)MA) copolymers was investigated by using small angle X-ray scattering, birefringence and rheometry. When the total molecular weight is judiciously controlled, the closed-loop consisting of a lower disorder-to-order transition and an upper order-to-disorder transition was observed. The phase behavior by including a random copolymer as one of the blocks was explained by a compressible mean field approach. We found that this block copolymer also exhibited excellent baroplasticity. |
