International ClassC08G 051/04AbstractThis invention is directed to the preparation of alloy articles consisting essentially of glass and/or glass-ceramic and an organic thermoplastic or thermosetting polymer having a working temperature compatible with that of the glass and/or the precursor glass for the glass-ceramic. The glass and polymer are combined at the working temperature to form an intimate mixture; i.e., the glass and polymer are in a sufficiently fluid state to be blended together to yield a body exhibiting an essentially uniform, fine-grained microstructure wherein, desirably, there is at least partial miscibility and/or a reaction between the glass and the polymer to promote adhesion and bonding therebetween. A body is shaped from the mixture and cooled to room temperature.Field of SearchMixing inorganic silicon-containing material having color or numerical limitations other than amount, e.g., included herein are m.p., chemical composition, particle size, surface area, etc., or composition or product thereof, DNRMMaterial contains glass Inorganic SI-O bond DNRM Glass and material other than glass (e.g., crystal glass, opal glass, etc.) Glass compositions, compositions containing glass other than those wherein glass is a bonding agent, or glass batch forming compositions Forming product or preform from molten glass Cooling of molten glass | |
