Relaxation of Molecular Conformation of Plasticized Poly (vinyl Chloride) (pvc)

The relaxation by creep recovery of plasticized poly lvinyl chloride) (PVC) was tested in relation to applied stresses and working temperatures. The relaxation time increased with stress but decreased with temperature. From the temperature dependence of relaxation times, an energy of 0.21 eV was found to activate the creep recovery process. It is thought that creep recovery is effected by the c...

Thermal transitions and extrusion of glycerol-plasticized whey protein mixtures.

The effects of glycerol and moisture contents on the thermal transitions of whey protein isolate (WPI) powder-glycerol-water mixtures were studied. Mixtures with ratios of 100:0, 70:30, 60:40, and 50:50 WPI:glycerol on a dry basis (db) were preconditioned to 0.34 +/- 0.01 (25.4 +/- 0.4 degrees C) and 0.48 +/- 0.02 (25.9 +/- 2.2 degrees C) water activity. Differential scanning calorimetry (DSC) ...

A PVC plasticized sensor for Ni(II) ion based on a simple ethylenediamine derivative.

A new PVC membrane ion selective electrode which is highly selective towards Ni(II) ions was constructed using a Schiff base containing a binaphthyl moiety as the ionophore. The sensor exhibited a good Nernstian response for nickel ions over the concentration range 1.0x10(-1)-5.0x10(-6) M with a lower limit of detection of 1.3x10(-6) M. It has a fast response time and can be used for a period o...

Biocomposites based on plasticized starch: thermal and mechanical behaviours

The paper is focusses on the study of the thermal and mechanical behaviour of reinforced agro-materials. Various formulations based on plasticized starch matrix have been carried out, varying matrix formulation, filler content, fibres length and nature. Cellulose and lignocellulose fibres, which show unequal surface tensions, have been tested. After extrusion and injection moulding, the propert...

Thermal and Dynamic-mechanical Properties of Wood-PVC Composites

The influence of maleation on thermal and dynamic-mechanical properties of wood-PVC composites was investigated in this study. Experimental results indicated that maleation had a significant influence on most of the properties for wood-PVC composites. Storage modulus (E’), loss modulus (E”), and complex modulus (E*) of resultant wood-PVC composites were related to the retention levels and graft...
