Measurements of stress and birefringence of networks of natural rubber and cis-1,4-polyisoprene deformed by simple elongation are reported. The experimental results are compared with theoretical calculations. It is found that the stress-strain relati

Polyvinyl fluoride (PVF) shows a strong crystal interference caused by the lateral distances of the chains, and is highly crystalline. Over the temperature range 0—100°C the degree of crystallinity is about 86%. Gelation of PVF in γ-butyrolactone

The phase behaviour of liquid crystalline side chain polymers is investigated by different experimental methods. PVT- and DSC-measurements as well as X-ray and optical investigations show that additionally to the known factors from low molecular weig

X-ray measurements as function of temperature were made from pure polyvinyl alcohol (PVA) and concentrated PVA-solutions in water, glycerine, and glycol. The solutions form gels at adequate low temperatures. As the formation of a chemically bound net

PVT-measurements on atactic polystyrene shows that the Ehrenfest equations, which describe a thermodynamic transformation of the second order, are not applicable for the glass transition. The introduction of one internal ordering parameter ζ in addi
