We developed and describe a differential scanning calorimetry method for calculating the initial crystallinity, change of crystallinity and crystallinity percentage of amorphous metal alloys as a function of temperature. Using thermodynamic enthalpie

Detailed knowledge on chain mobility in polymers is of fundamental interest in order to understand their mechanical properties. As a specific example, the melting behavior of semicrystalline polyethylene can be studied by thermal analysis and NMR spe
Clearly divided into three parts, this practical book begins by dealing with all fundamental aspects of calorimetry. The second part looks at the equipment used and new developments. The third and final section provides measurement guidelines in orde

Recently we demonstrated that it is possible to obtain single chains forming single crystals, where chains are adjacently re-entrant. It is feasible to melt these crystals, either by simple consecutive detachment of chain stems from the crystalline s

Coatings and engineering plastics often require high impact strength. This property can be achieved with tougheners. For the present paper, core-shell impact modifiers were synthesized using ethylene–propylene copolymers (EPM), ethylene–propylene

Another thermodynamic approach to the Gibbs–Thomson equation, starting from an incremental composition of enthalpy and entropy of the chain molecule, is presented. This describes the melting temperature of (lamella) crystals of linear, folded and c

Poly[(butadiene-alt-ethene)-co-(butadiene-alt-1-olefin)] terpolymers were synthesized by Ziegler-Natta polymerization using VO(O-neopentyl) 2 Cl/Al(i-Bu) 3 catalyst system in toluene. Variation of the 1-olefin/ethene ratio in the monomer feed produce

The crystallization behaviour of the series of hydrogenated poly(butadiene-alt-ethene) to poly[butadiene-alt-(1-hexadecene)] copolymers was investigated with the aid of differential scanning calorimetry (DSC) and X-ray measurements. Hydrogenated poly

Viele organische und makromolekulare Stoffe neigen dazu, bei Abkuhlung glasig zu erstarren. Beim Erwarmen erweichen die Materialien in einem Temperaturbereich und verandern dabei ihre Materialeigenschaften. Kenntnisse uber diesen Glasubergang haben i
