Zusammenfassung:The products have been characterized by gel filtration, NMR, and differential scanning calorimetry. The influence of initiator, reaction conditions and monomer structure is analysed in detail. Detailed microstructures can be deduced from NMR spectra and apparent anomalies are accommodated in terms of the \#g\-\+i\gauche\-i\ effect established by Tonelli. (Original abstract-amended)
