Scattering Behavior of Distorted Semi-Flexible Polymers and Semi-Flexible Random Copolymers — •Reinhard Sigel — Max-Planck-Institut für Eisenforschung, Düsseldorf

Models for the interpretation of scattering experiments for two classes of polymer systems are discussed. In distorted semi-flexible polymers, the orientation correlation of the chain gets lost at distortions (kinks). A statistical combination of different monomers results in a random copolymer, where the orientation correlation is affected by the persistence lengths of the respective homo-polymers. In a dilute solution condition, the description of both polymer systems can be traced back to suitable averages of form factors from the literature. To handle the contrast difference in random copolymers, the approach of Endo and Shibayama (Polymer J. 42, 157-160, 2010) for flexible chains is extended to the case of semi-flexible chains.
