Which terms are matched correctly with their definitions?
I. Crystalline domain - order regions in the solid state of a polymer.
II. Amorphous domain - disordered regions in the solid state of a polymer.
III. Melt transition temperature - temperature at which a polymer undergoes the transition from
Hard to rubbery state.
IV. Glass transition temperature - temperature at which glass polymers melt.

Question

Quizplus · Accepted Answer

I. Crystalline domains refer to ordered regions within polymers, where the polymer chains are arranged in a regular, repeating pattern. II. Amorphous domains are the opposite, representing disordered, non-crystalline regions within polymers where the chains do not have a regular arrangement. III is incorrect because the melt transition temperature is the temperature at which a polymer changes from a solid to a molten or liquid state, not specifically from hard to rubbery. IV is incorrect because the glass transition temperature is the temperature at which an amorphous polymer (or an amorphous region within a polymer) transitions from a hard, glassy state to a soft, rubbery state, not the temperature at which glass polymers melt.
