In order to study the anharmonic elastic behaviour of solid polymers, we introduce a Brillouin technique, including the appropriate theoretical background, to obtain the complete tensor of elastic stiffness constants of third-order. First results are

Die elastische Lichtstreuung wird in vielen Gebieten der Polymerwissenschaft angewendet, um Strukturen in der Grosenordnung 102 – 105 A zu Charakterisieren. Mit dieser Methode konnen sowohl Dichte- als auch Anisotropiefluktuationen erfast werden, s

Two-dimensional magic-angle-spinning (2D-MAS) NMR has been used to measure the orientation parameter, P2, of the diphenylene propane unit in bisphenol-A polycarbonate oriented by stretching to various extension ratios,λ, atT=295K andT= 403 K.P 2 is

Birefringence, anisotropic heat conduction, and wide angle X-ray scattering (WAXS) investigations have been performed on one set of uniaxially drawn samples of polycarbonate (PC). The orientation parameters from heat conduction and from WAXS are well

The changes in molecular orientation occurring during craze initiation and growth are discussed. Craze initiation is considered as a stress-induced, rotational, collective reorganisation of stiff chain sections in volume elements having a particularl

It is demonstrated that under appropriate deformation conditions intrinsic crazes (crazes II) are initiated in unoriented and pre-oriented polycarbonate which is stretched to its natural draw ratio. Molecular disentanglement is proposed as the mechan

The physical structure of the melt, the supercooled melt, and the glassy state of amorphous polymers can be characterized by the chain conformation, the local order, and the morphology. The conformation was studied by small-angle neutron scattering.
