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?
