On which factors does the the capacity of an adsorbent depends?

Question: Briefly explain how each of the following influences the tensile or yield strength of a semicrystalline polymer and why:               (a)  Deformation by drawing             (b)  Annealing of an undeformed material

Food storage containers are rigid.As a result, they can keep their shape to hold food.When food storage containers are heated in a microwave oven, they become more flexible.Why? There is an increase in molecular motion and the intermolecular force of attraction between polymers weakens. The polymer chains decrease in length  There is more cross-linking between the monomers The polymers break down into monomers
