Impact resistant hydrophobic high heat optical acrylic copolymers

Abstract

The invention relates to impact resistant acrylic copolymers and terpolymers incorporating high Tg, hydrophobic (meth)acrylates and derivatives that have high thermal stability and excellent impact resistance. These copolymers have a Tg of 114-130° C., along with high molecular weight and high impact resistance. The copolymer is found to exhibit high heat resistance, high light transmission, low haze, low moisture uptake, excellent environmental stability, excellent high temperature thermal stability, and excellent mechanical properties, along with excellent UV resistance. The copolymer, or terpolymer may be used in many applications, including, but not limited to automotive parts, lighting pipes, thin wall parts, optical lenses, extruded optical films, (co-)extruded sheets/profiles, thermo-formable sheets, injection molded parts, and composites.
