Question

Quizplus · Accepted Answer

Dibutyl phthalate is a plasticizer that can cause a poly(methyl methacrylate) (PMMA) to become rubbery. This is because the plasticizer molecules disrupt the polymer chains, reducing the intermolecular forces and increasing the free volume between the chains. This allows the polymer to move more easily and become more flexible and rubbery.
