Answer
Changes in the polymer structure that can increase its rigidity and raise the melting point include introducing
(1) cross-linking between polymer chains,
(2) bulky substituents or branches on the chains, and
(3) groups that can interact by strong intermolecular forces such as hydrogen bonding.
