Abstract

Embodiments described herein are directed to oligomeric phosphonates and polyphosphonates that have non-reactive end groups, methods for making such oligomeric phosphonates and polyphosphonates, and compositions containing such oligomeric phosphonates and polyphosphonates. The oligomeric phosphonates and polyphosphonates of such embodiments may be incorporated into engineering polymeric into which they are mixed to make polymer compositions having good flame retardancy and mechanical properties.
