Which one of the following is not an example of a condensation polymer?
(1) Terylene
(2) Nylon 6,6
(3) Bakelite
(4) Polystyrene
Polystyrene
Polystyrene is a polymer formed by the addition polymerization of styrene monomers. It does not involve the elimination of small molecules like water, which is characteristic of condensation polymers. In contrast, Terylene, Nylon 6,6, and Bakelite are all examples of condensation polymers.
The following graph indicates the system containing 1 mole of gas involving various steps. When it moves from Z to X, the type of undergoing process is:
