Polymer StructureThe structures of polymeric repeat units determine their stiffness, polarity and intermolecular bonding. Incorporation of stiff side groups or rigid aromatic rings into a polymer repeat increase the modulus (stiffness) of the molten and solid polymer as well as increasing its critical transition temperature. Thus, polyethylene¡¯s Tg is about -120¡ãC, while ……

Polymer MaterialsNote: a good introduction to polymers can be found at http://www.pslc.ws/macrog/index.htmPolymers are long chain molecules made up of simple repeating molecular units (i.e., mers). The net effects of having long chains are chain entanglement, a summation of intermolecular forces, and time scale of motion[33]. Several factors, including the polymer¡¯s molecular weight an……
