Question

The immiscible blends exhibit ____________

(a) Excellent mechanical properties

(b) Poor mechanical properties

(c) Poor chemical properties

(d) Intermediate chemical properties

This question was posed to me during an interview.

This is a very interesting question from Polymer Blends in chapter Polymers of Engineering Chemistry I

Answer 1

Correct answer is (b) Poor mechanical properties

Best explanation: The immiscible blends exhibit poor mechanical properties. This is by far the most populous group. If the blend is made of two polymers, two glass transition temperatures will be observed.
