1. The problem statement, all variables and given/known data Topic : Idendification of different types of polymer Suggested materials : Plastic bottles or materials Sugeested methods of analysis : Volumetric analysis, Chromatography ,pH, Solvent extration, Distillation General purpose of project : To inculcate awareness on health and environment, To instill good moral values, To apply basic scientific skill and to apply the basic chemical principle in investigation 2. Relevant equations Polymer 3. The attempt at a solution This is my project in my Year-2.Polymer is a large molecule, or macromolecule, composed of many repeated subunits. Here is my thought to coursework: Prepare few types of plastic cup, polystrene cup. Add water with high temperature (preffered boiling water) into the polymer cup My problem is, is there any chemical reaction during hot water with polymer cup ? I knew that its dangerous when we drink hot water in plastic cup, but it seems nothing related to chemistry. Is the pH value will change if hot water is in plastic cup? If not, is there any experiment that related to polymer that i can carry up ? Because the only experiment i can think is temperature affecting the polymer.
