The method of semiempiric-atomistic calculations is applied to a polydiene. For this purpose a Coulomb term has to be added to a potential set used successfully for polyolefines. All stable 4 *p/q helices of poly(trans-1,4-butadiene) are calculated.

A model is proposed for the electrical polarization that causes the orientation and, hence, the electric birefringence of a suspension containing single crystals of a poly(ethylene oxide)–polystyrene diblock copolymer or a poly(ethylene oxide) homo

The plasma treatments, corona and low-pressure plasma, were applied to two so-called high-performance thermoplastics, polyetherimide ( pei ), a liquid crystalline polymer ( lcp ) and, for comparison, to polypropylene ( pp ). The treated surfaces were

Using high pressure dilatometers, the specific volume of isotactic polypropylene has been measured as a function of temperature and pressure up to 3.5 kbar. Up to 1 kbar this has been done not only for a commercial whole polymer, but also for sharp f

The temperature and pressure dependence of the translational B1u-lattice vibration has been determined in the pressure range of 7 kbar and a temperature range of almost 200 K from room temperature upwards. For some pressure values the Gruneisen Param

Based on a Grubb-Parsons cube interferometer an instrument was developed for use with a high pressure optical cell. The light from the lamp is made parallel and, after interference, focussed on to a sample of approximately 2.5 mm dia between diamond

High pressure dilatometry is used to study the melting processes and the melt of isotactic polybutene-1. Evaluating a great number of isobaricV(T)-curves determined in the range of a few hundred bar the pressure dependence of the melting temperature
