WebNov 13, 2015 · Other polymers may not be birefringent (evidenced by the polycarbonate specimen illustrated in center photomicrograph), and do not display substantial secondary or tertiary structure. In other cases, both … 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, the chains rearrange upon freezing and form partly ordered regions with a typical size of the order 1 micrometer. Although it would be energetically favorable fo…
