METHODS FOR THE MANUFACTURE OF POLYCARBONATE COMPOSITIONS, THE COMPOSITIONS FORMED THEREBY, AND ARTICLES THEREOF

摘要

A method of making a thermoplastic composition comprises melt blending a reaction mixture comprising a first polycarbonate comprising repeat units derived from monoaryl monomers (II) and (III) and a diaryl monomer (IV), wherein the sum of the mole percent of the repeat units derived from monomers (II) and (III) is greater than or equal to 30 mole percent, and the mole percent of the repeat units derived from monomer (IV) is 5 to 70 mole percent, each based on the total moles the repeat units derived from monomers (II), (III), and (IV), and the total weight of the repeat units derived from monomers (II), (III), and (IV) is greater than or equal to 90 wt. % of the first polycarbonate; and an additional polycarbonate, comprising 50 to 100 mole percent of repeat units derived from a bisphenol cyclohexane.
