Abstract

To determine the compatibility between the rigid rod and the flexible chain polyquinolines, both small angle x-ray and neutron scattering measurements were conducted on a sample containing deuterated flexible components. The scattering intensities from both x-ray and neutron were reduced to absolute scale in order to remove the scattering contribution from microvoids which tended to overshadow the signal of molecular origin. Quantitative information regarding the extent of molecular segregation in a polyquinoline multi-block copolymer was obtained, the result indicated that the material was strongly associated but not segregated into single component phases.
