Answer
Tensile modulus increases with increasing degree of crystallinity for semicrystalline polymers. This is because of the enhanced secondary interchain bonding which results from adjacent aligned chain segments as percent crystallinity increases. This enhanced interchain bonding inhibits relative interchain motion.
