ABSTRACT
Bisphenol A polycarbonate (BPA-PC) [1] is an engineering thermoplastic that has many uses in building and construction, automotive, and consumer products. The material is usually extruded or injection-molded and, under these conditions, is totally amorphous. The rigidity of the polycarbonate chain, which results in a glass transition temperature within 1 00°C of the melting point, does not allow crystalline material to nucleate and grow as it cools from the melt. However, poly carbonate can be prepared under conditions that produce crystalline material. The preparation of this material and its properties is the subject of this chapter.
