The structural order of some novel ionic polymers, 2. Models of molecular packing

The molecular packing and spatial correlations of two isomeric zwitterionic polymethacrylates and one polyacrylate analog are studied by means of X‐ray analysis and conformational calculations. The analysis of the correlation functions and density distribution profiles suggest a double‐layered molecular packing which is discussed for the three polymers investigated, with respect to their different chemical structures. Whereas the zwitterionic polymethacrylates studied exhibit liquid‐like short‐range order, the polyacrylate analog exhibits an ordered double‐layered superstructure.
