The incorporated ring ,structure, gives COCs their stiffness, while its size prevents the molecules from becoming ordered enough to crystallize. The total absence of crystallinity ensures very high transparency. Because the copolymers are olefinic, they have low densities, close to 1.0, resulting in a very high stiffness-to-weight ratio.
