Systematically varying the ratio of 1 , 2 - / 1 , 4 - microstructures of poly ( 1 , 3 - cyclohexadiene ) , we have studied the effects of conformational asymmetry among the three blocks on the morphologies using transmission electron microscopy ( TEM ) , small - angle X - ray scattering ( SAXS ) , and self - consistent field theory ( SCFT ) performed with PolySwift + + .
