Patent number: 6268425Abstract: This invention is directed to the preparation of alloy articles consisting essentially of 65 wt. % or more glass and high temperature organic thermoplastic or thermosetting polymers having working temperatures which are 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.Type: GrantFiled: January 11, 1999Date of Patent: July 31, 2001Assignee: Corning IncorporatedInventors: Paul D. Frayer, Roy J. Monahan, Michelle D. Pierson
