What are the disadvantages of polymers? What is an electrical
property of a polymer and is there any exception to that electrical
property? if so, what is it?
For Polymers lab. In what region of the two-phase system was the
Nylon-6,10 polymer formed after the sebacoyl chloride/cyclohexane
and 1,6-hexanediamine/sodium hydroxide solutions were mixed?
Why?
Mixtures of two different polymers belong to the class of
polymer blends.
a) Explain why a two-phase system can form when mixing two
different polymers. Give two examples of morphology types that may
occur (sketch).
b) Show by example how the morphology of a blend influences the
macroscopic properties of the blend.
Define the glass transition temperature of polymers. If a polymer
has a glass transition temperature of 25 °C, would you expect it to
be a glassy polymer at room temperature?
A) Explain the general responses of ceramics, metals and
polymers to mechanical and electrical loads in terms of both
primary and secondly chemical bonds
B) Classify the following materials as a polymer, metal,
ceramic, or composite: Boron Nitride, Bricks, Plexiglas, Concrete
and Manganese.
