Title: Processing organic polymers with hydrated glasses

Abstract: This invention relates to the coprocessing of hydrated glass with organic polymers to form integral bodies which can be stronger, tougher, and more durable than the original hydrated glass and stiffer than the original plastic material. The process is amenable to any hydrated glass so long as the processing temperature of the hydrated glass is below the temperature at which decomposition of the organic polymer takes place. Chemical bonding between the hydrated glass and a thermosetting organic polymer is achieved through the use of silane coupling agents. Such are not necessary with thermoplastic polymers. The invention is applicable with both thermosetting and thermoplastic polymers which are resistant to alkali environments.
