主权利要求

(WO2016189494) 1. A polymer blend comprising a polymer derived from melt extrusion of (i) 80 to 95 wt% polycarbonate; said polycarbonate having and end cap level of 45% to 80% and a branching level of 300 - 5,000 ppm comprising the following branching structures: (ii) 4.9 to 20 wt% polymethyl methacrylate; and (iii) 0.1 to 1.5 wt% of catalyst; wherein said polymer is transparent, wherein transesterification occurs with at least a portion of the polycarbonate and the polymethyl methacrylate during melt extrusion to produce a transesterification polymer; and wherein the combined wt% value of all components does not exceed 100 wt. %, and wherein all wt% values are based on the total weight of the composition.  9. A method of forming an article comprising: (a) melt extrusion of (i) 80 to 95 wt% polycarbonate; said polycarbonate having and end cap level of 45% to 80% and a branching level of 300 - 5,000 ppm (ii) 4.9 to 20 wt% polymethyl methacrylate; and (iii) 0.1 to 1.5 wt% of catalyst to produce a transparent polymer blend; wherein said polymer is transparent, wherein transesterification occurs with at least a portion of the polycarbonate and the polymethyl methacrylate during melt extrusion; and wherein the combined wt% value of all components does not exceed 100 wt. , and wherein all wt% values are based on the total weight of the composition and (b) molding the polymer blend into said article.
