The Improvement of Polyvinyl Chloride Synthesis Using Different Approaches
Abstract: Polyvinyl chloride (PVC) is produced by the polymerization of the vinyl chloride monomer either by direct chlorination of olefins or by addition of hydrogen chloride to acetylene. The polymerization conditions are: heat, peroxides or oxidizing agents with basic structure as -CH2CHCl.CHCl-CH2.CHCl-. Polyvinyl chloride is a thermoplastic and its plasticity can be increased by incorporating ‘plasticizers’ of relatively low molecular weight organic materials during molding or extrusion. PVC has high hardness …

Review of Silicon Reactivity of Self-assembled monolayer and its Properties
Abstract: In most cases, the assumption of perfect high viscosity between silicon and silver underlies the modelization of silicene on Ag(111). According to recent reports, growth does not take place on top of the Ag(111) terraces, but rather within the first layer of them. In this article, we present the results of a study that combines scanning tunnelling microscopy and density functional theory to simulate the nucleation process and reveal the …
