Abstract : It was shown in work that the properties of isotactic high molecular weight polymethylmethacrylate PMMA differ from the properties of isotactic low molecular weight PMMA and we hypothesized that there are stereo complexes in a solution of PMMA with a content of 70% isotactic stereo isomer. Intending to study the state of high molecular weight isotactic PMMA in dilute solutions we studied in the influence of temperature on their light refringence, their birefringence in when flowing and their viscosity.
