is the chemical formula for PVC that consists of Carbon‚ Hydrogen and Chloride. PVC is a thermoplastic polymer meaning that is recyclable‚ the addition of the chlorine atom allow for easier identification during automated sorting systems and with today’s society being environmentally concise these become important properties. Other important properties of PVC that make it a desirable polymer are its resistance to chemicals and corrosion‚ good electrical and thermal insulator‚ fire retardant (burns

Problem #1 a) Describe the difference between the substitutional and the interstitial mechanism for mass transport - diffusion in metals. b) Do these two mechanisms control mass transport – diffusion in 1) ceramics and 2) polymers? Explain your answers. c) Given the table of data below‚ which metal (iron - Fe‚ tungsten - W‚ or copper - Cu) has the highest self diffusion coefficient‚ D‚ at 950oC. Explain your reasoning.

portions of these are combinations of synthetic fibers woven or threaded together to make a final product. These synthetic fibers are a large group of polymers. Synthetic polymers offer more possibilities‚ since they can be designed with molecular structures that impart properties for desired end uses. All fibers are ploy-something or polymers. That means they are long strings of repeating chemical elements. Some fibers come from ground plants that synthesize connected units of cellulose like

When incorporated into polymer or ceramic materials these properties manifest as remarkable improvements in the host material. Graphene based polymer composite exhibit extraordinary low material percolation threshold (o.1 vol%) due to large conductivity and aspect ratio of graphene sheets. The mechanical and thermal properties of these materials rank among the best in comparison with other carbon based composites due to strong interactions between polymer hosts and graphene sheets.

reflecting optical microscopy methods‚ and a detailed analysis of the distinct microstructure of metal‚ ceramic‚ and polymer materials. For metals and ceramics‚ preparation procedures include grinding‚ polishing‚ and surface treatment (etching) which may vary in different samples. Generally‚ for opaque materials as such‚ the samples are viewed in reflecting mode. In the case of polymers‚ samples are sliced into very thin layers for viewing in transmitting mode‚ due to their translucent properties to

Chemical reaction‚is the process by which one or more substances are converted into one or more different substances.Old bonds break and new bonds form. The original substances are called reactants. The resulting substances are called products. It is a simple chemical reaction. Another simple reaction might involve a reactant molecule breaking apart. Many enduring substances such as rock and water are highly

------------------------------------------------- Liquid–liquid extraction From Wikipedia‚ the free encyclopedia Liquid–liquid extraction also known as solvent extraction and partitioning‚ is a method to separate compounds based on their relative solubilities in two different immiscible liquids‚ usually water and an organic solvent. It is an extraction of a substance from one liquid into another liquid phase. Liquid–liquid extraction is a basic technique in chemical laboratories‚ where it is performed
