The effect of melamine polyphosphate (MpolyP) on the thermal degradation of both polyamide 66 (PA66) and polyamide 6 (PA6) was studied using a combination of solid-state techniques. The mixtures of MpolyP with polyamides were heated for different tim

The kinetics of physical gelation and the structure of telechelic ionomers have been studied by 1H and 13C solid-state NMR, SAXS, and WAXD. The reaction of MgO with unsaturated polyesters containing carboxylic and hydroxyl end groups leads to about a

A series of side chain dendritic polymers (SCDP) was produced by copolymerization of dendritic diols of the second, third, and fourth generation with four different semirigid and flexible diisocyan...

The esterification kinetics of isophthalic and terephthalic acid, with benzyl alcohol, were studied in the melt phase, which is a heterogeneous system because of the low solubilities of the phthalic acids. The relative concentrations of components an

A multi-purpose computer program has been developed for describing copolymerization and network formation in step reactions. It operates at two hierarchical levels: a generation level and an application level. At the generation level, the class of pr

Programs have been written to calculate TDS corrections from Long Wave eigenvectors and modelled frequency Dispersion of the acoustic branches (LWD approximation). Calculations on naphthalene crystals with neutral and with charged atoms were carried

Solution-crystallized ultra-high molecular weight polyethylene (UHMW-PE) can be drawn in the solid state to very high draw ratios, leading to materials with excellent mechanical properties. Very recently, the drawing process has been studied via diff

The influence of solid state drawing of solution-crystallized ultra-high molecular weight polyethylene on the structure has been studied. Results obtained by different wide-angle and small-angle X-ray techniques support a deformation mechanism, which

In the past morphological changes, caused by uni-axial drawing of flexible polymers have been studied mostly under conditions, quite different from the drawing conditions. This could give rise to certain artefacts, leading to mis-interpretations. Up

Potential-energy calculations have shown that the crystal structure reported by Marck & Poland I Z. Kristallogr. (1925), 62, 103-1121 is not favourable for ethane. For the phase stable between 89.726 and 89.834 K at very low pressures, a disordered s
