Abstract:
1. A method of making a thermoplastic composition, the method comprising reacting a melt reaction mixture comprising: a first polycarbonate comprising repeat units derived from monomers (II), (III), and (IV), wherein monomer (III) is a second dihydroxy compound not the same as monomer (II) and of the formula: wherein m is 1 to 4, and R monomer (IV) is a third dihydroxy compound of the formula: wherein R 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, based on the total moles of the repeat units derived from monomers (II), (III), and (IV) in the first polycarbonate, the mole percent of the repeat units derived from monomer (IV) is 5 to 70 mole percent, 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 in the presence of a catalyst for the reaction of the first polycarbonate and the additional polycarbonate.
