Characterization of poly(vinyl chloride) powder produced by emulsion polymerization
The effect of emulsion process formulation ingredients on the morphology, structure, and properties of polyvinyl chloride (PVC) powder has been considered in this study. PVC powder was extracted with ethanol and films were ...
Thermal behaviour of metal soaps from biodegradable rubber seed oil
Soaps are a class of surface active compounds derived from natural oils and fats. Double decomposition reactions permit the synthesis of metallic soaps, which are long-chain carboxylates of metal ions, from alkaline ones ...
Batch and column studies on heavy metal removal using a local zeolitic tuff
Ion exchange is considered to be one of the most cost effective methods if low cost ion exchangers such as natural zeolites are used in waste water treatment. In this study, a zeolitic tuff rich in clinoptilolite from ...
Statistical thermal stability of PVC
Experimental design was used to optimize the processing parameters for the decomposition of poly (vinyl chloride). Factorial design and face centered composite design (FCC) were applied to determine the optimum conditions. ...
The influence of binder content on the water transport properties of waterborne acrylic paints
Diffusion coefficients and sorption isotherms of water in waterborne acrylic paint films and in the pure binder of the paints have been measured by gravimetric sorption. Solubility of water was found to enhance with the ...
Preparation and characterization of calcium stearate powders and films prepared by precipitation and Langmuir-Blodgett techniques
(American Chemical Society, 2010-02)
The preparation of calcium stearate (CaSt2) using precipitation and Langmuir-Blodgett techniques was investigated in this study. While sodium stearate and calcium chloride were used in the precipitation process, calcium ...
