This presentation is part of: Inorganic and Organometallic Polymers I

New Hybrid Polymer Systems and Materials

Harry R. Allcock, The Pennsylvania State University, PA

The incorporation of inorganic elements into polymers offers the prospect of properties that combine the advantages of ceramics, semiconductors, metals, or optical materials with the characteristics of classical organic polymers. The polyphosphazene system allows this to be accomplished in two different ways. First, the use of organic or organometallic side groups linked to a polyphosphazene chain allows property tuning in ways that are almost unprecedented, and this has led to the synthesis and study of more than 700 different polymers. Second, recent research has provided ways to link polyphosphazenes to classical organic polymers such as polystyrene, poly(ethylene oxide), or polynorbornene, or to polysiloxanes (silicones) via block copolymer or comb architectures, a method that permits a genuine hybridization of the inorganic and the organic systems. This talk will discuss both the synthetic and polymer design aspects of this field.
