Question

For amorphous and semi-crystalline polymers, mixing leads to the formation of ____________

(a) Mechanical blends

(b) Solution-cast blends

(c) Latex blends

(d) Chemical blends

This question was addressed to me in an online interview.

This intriguing question comes from Polymer Blends in section Polymers of Engineering Chemistry I

Answer 1

Right option is (a) Mechanical blends

Easiest explanation: For amorphous and semi-crystalline polymers, mixing leads to the formation of mechanical blends. The macroscopically uniform properties are usually caused by sufficiently strong interactions between the component polymers.
