Abstract
Acid-functionalized copolymers of methyl methacrylate having relatively high glass transition temperatures and molecular weights may be employed to manufacture articles having high light transmission values, low haze, high heat resistance, and high environmental stability, which are useful as optical protection films, zero-zero optical retardation films, and compensation films as well as lighting pipes and optical imaging lenses.
