摘要:
Polycarbonate compositions having an aromatic polycarbonate resin with 90% or greater fluoroalkylene carbonate end-groups are formed from a partially fluorinated alcohol or a partially fluorinated polymeric alcohol, and a bisphenol and a carbonate source using melt or interfacial polymerization methods. Copolymers and blends with a variety of other bisphenols and other thermoplastics are also described. The polycarbonate compositions show high water contact angles, fluorine enrichment on the surface layer of molded articles, and good flame retardant properties and are useful in a variety of applications including medical, automotive, telecommunication and weatherable applications.
