Changes occurring in the chemical structure of polyvinyl chloride during chlorinationA study has been made of changes in the concentration, distribution and chemical structure of unsaturated groups during the chlorination of PVC. It was found that such changes occur irrespective of the method and ...

The chemical dehydrochlorination of polyvinyl chloride was studied in solution in tetrahydrofuran. The dehydrochlorinated products were characterized by their chlorine contents and by UV/visible spectroscopy. The absorption spectra of dehydrochlorinated PVC consist of a series of absorption maxima between ...

Re: Corrosion resistance of PVC «Reply #1 on:September 26, 2012, 07:51:44 AM » 1) What is the chemical structure of polyvinyl chloride? 2) What do you know about the chemical reactivity of that type of structure? Logged kanaka@mme ...
Chemical and microbial modifications are not common with polyvinyl chloride (PVC). This paper presents a novel green hybrid technique for the PVC degradation using biodegradation followed by chemical modification, using glycerol and urea (C-PVC).Mucor rouxiispecie is found to be susceptible towards C...
This simple structure, repeated thousands or even millions of times, yields long, chainlike molecules of varyingmolecular weight, with or without attached side branches, that exhibit looselyamorphousor closely ordered, semicrystalline arrangements. Polyolefins are lightweight, flexible, thermoplastic materials...
