    Polymers are made up of large molecules that are chemically formed by thousands of molecules called "monomers." Polymers are amorphous solids- meaning they have no definite shape and they can take form of different volumes. Borax is another ingredient to make a polymer. Adding borax to the glue mixture, the molecules that go through the polymer chain, link together, forming a gooey slime. The polymer link is not very strong, so it can stretch and bend. I predicted that adding more borax in the...

    22-2-96 CONDUCTING POLYMERS By Colin Pratt INTRODUCTION Until about 30 years ago all carbon based polymers were rigidly regarded as insulators. The idea that plastics could be made to conduct electricity would have been considered to be absurd. Indeed, plastics have been extensively used by the electronics industry because of this very property. They were utilized as inactive packaging and insulating material. This very narrow perspective is rapidly changing as a new class of polymer...

    Effect of Temperature on Polymers: Solids on heating eventually melt to form a liquid. With polymers it is not so simple rubber on cooling (in liquid nitrogen) becomes brittle or glassy. Many polymers have a mixture of ordered (crystalline) regions and random (amorphous) regions. In the glassy state, the tangled chains in the amorphous region are frozen so movement of chains is not possible the polymer is brittle. If the glassy material is heated, the chains reach a temperature at which...
