  • Publication number: 20070290405
    Abstract: The present invention discloses the miscibility of inorganic phosphate glass and organic polymer prepared by blending both components in the liquid phase using conventional polymer processing methods. By utilizing low Tg phosphate glasses to plasticize nylon, e.g. polyamide 6, a new class of plasticizer is introduced that allows for the creation of unique nylon polymer composites. These materials display tunable morphologies, interesting properties, and significant reduction in flammability, while easing the processing of nylon through a substantial reduction of viscosity. The addition of a low Tg phosphate glass in small amounts (less than 10% by volume) to a nylon matrix results in a drastic reduction in viscosity and a decrease in the nylon glass transition temperature and flammability, with the capability of adding a low Tg phosphate glass up to 60% by volume. The observed mechanical properties of the nylon/phosphate glass hybrid are consistent with that of plasticized polymers.
