Today this polymer is used in all sorts of applications. The formation of plexiglass was begun in 1930‚ at McGi11 University by William Chalmers‚ a research student. He polymerized methacrylic ethyl ester and methacrylic nitirile‚ creating a clear plastic paste. Later‚ in 1936‚ Walter Bauer and Otto Rohm accidentally developed plexiglass by pouring the gum between two sheets of glass. The gum hardened and separated cleanly from the glass sheets. They created plexiglass as we know it today. Since its

Background Theory. Polyethylene Polyethyene is a type of polymer that is used in our daily life. Polyethylene(abbreviated PE) is a thermoplastic polymer‚ meaning that is can be melted to a liquid state and remolded as it returns to a solid state. PE is chemically synthesized from ethylene‚ a compound that is usually made from petroleum or natural gas[1]. The main mechanical properties of PE are the ultimate tensile strength and the modulus of elasticity. There are different types of Polyethylene
