Abstract
Abstract Stable conformations and their sequential order of isotactic (IPS), syndiotatic (SPS) and atactic polystyrenes (APS) in various aggregation states have been investigated by infrared (IR) spectroscopy, 13 C NMR and X-ray diffraction. It has been demostrated that the partially ordered skeletal conformation existing in IPS/CS 2 gels is of a (3/1) helix (TG) type having the pendant phenyl groups oriented in a disordered fashion, rather than the near- ...
