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.

Abstract: An optical adhesive product and a process for manufacturing an optical adhesive product, laminated film ensembles, and laminated lenses. The optical adhesive product includes a glyoxal water solution that is pH adjusted for use as an optical adhesive that demonstrates a wet peel force strength above about 6 Newtons. A water based polymer, such as PVOH, may be added to the adhesive system. According to the process, the glyoxal adhesive system is manufactured and utilized to laminate TAC-PVA-TAC films together to form a polar film ensemble. The polar film ensemble is laminated to an optical susbtrate and in the case of an ophthalmic lens, surfaced, coated and edged. The optical adhesive product avoids film separation in the polar TAC-PAV- TAC film ensemble during edging.

Abstract: Curved lenses configured to decode three dimensional content and method of fabricating the same. The lenses comprise a polyvinylalcohol polarizer film or similar type of material laminated with triacetate or similar type material on one or both sides, wherein the polarizer film has a polarizing efficiency equal to or exceeding 99% and a transmittance percentage equal to or exceeding 35% and a retarder film (e.g., norbornene copolymer resin) laminated on a front surface of the polyvinylalcohol polarizer film laminated with triacetate and aligned to produce a desired circular polarization responsive to specified retardation wavelengths. Thermo forming and press polishing techniques may be used to fabricate/curve the blanks into lenses. The lenses (optical elements) may be used in an injection molding process to add thickness.
