ABSTRACT:
The invention relates to a high optical purity toughened copolymer film or coating. The copolymer is a graft or block copolymer, preferably acrylic, preferably produced by a controlled radical polymerization having an extremely low degree of particulate contamination and excellent optical properties. The film or coating is preferably formed by solvent-casting on a temporary substrate or solvent-coating on a permanent substrate.
