SUPER HIGH-FLOW POLYCARBONATE COPOLYMERS: DEVELOPMENT AND OVERVIEW OF PHYSICAL AND MECHANICAL PROPERTIES

摘要

A new super high-flow polycarbonate copolymer derived from bisphenol-A (BPA) and specific bio-sourced monomer derived from castor bean oil is reported. This copolymer belongs to the class of Lexan~* HFD resins known for their improved melt flow and ductility balance compared to standard polycarbonate yet with similar high optical clarity and light transmission properties. These super high-flow HFD copolymers are designed to have all attributes of the Lexan~*HFD resins such as lower temperature processing capability, longer injection molding flow lengths and improved low temperature ductility versus a standard polycarbonate material but with superior flow characteristics as the name suggests. The superior flow would enable molding of thinner parts with similar practical impact to standard PC.
