Description
Summary:Polymer is a macromolecule, composed of many repeated subunits. Polystyrene is a polymer of styrene. Polystyrene has very low impact strength. Polystyrene generally leads to lower tensile strength, crystal grades being stiff and brittle. It is used to construct clamshell packs, cookie trays, cups, forks, spoons, cushioning materials for packaging, disposable medical devices, egg cartons, fast food containers, lids, lunch boxes, meat trays and also used in civil construction (concrete form-work or weight reduction on foundations). In the present study an attempt has been made to compute the viscosity of Polystyrene (PS 35000) in toluene and benzene in different concentrations (0.5%, 1.0%, 1.5%, 2.0% & 2.5%) at different temperatures (303 K, 308 K, 313 K & 318 K). From these experimental data the activation energy is calculated and the effect of solvent is analysed.
