A constant force applied to a polymer at temperatures above T g results in a viscoelastic deformation, i.e., the polymer begins to creep. See more Crystallization of polymers is a process associated with partial alignment of their molecular chains. These chains fold together and form ordered regions called lamellae, which compose larger spheroidal structures named See more Solidification from the melt Polymers are composed of long molecular chains which form irregular, entangled coils in the melt. Some polymers retain such a disordered structure upon freezing and readily convert into amorphous solids. In other polymers, … See more • Liquid crystal polymer • Modeling of polymer crystals See more The fraction of the ordered molecules in polymer is characterized by the degree of crystallinity, which typically ranges between 10% and … See more Thermal and mechanical properties Below their glass transition temperature, amorphous polymers are usually hard and brittle because of the low mobility of their molecules. … See more shark fishing charters uk
