Abstract: A thermoplastic composition including a resin phase and 10% to 55%, especially 25% to 45% of glass fibers by weight of the composition is disclosed. The resin phase includes a polysiloxane block copolymer including polydimethylsiloxane blocks and polycarbonate blocks derived from bisphenol A. The resin phase further includes a polycarbonate and has between 2.0 wt % and 10 wt % by weight of siloxane. The thermoplastic composition has (i) a notched Izod impact strength of at least 150 Joules per meter measured at 23° C. according to ASTM D256, (ii) a tensile strength greater than 95 MPa as determined by ASTM D638, (iii) a tensile modulus greater than 10,900 MPa as determined by ASTM D638 and (iv) an unnotched Izod impact strength greater than 775 Joules per meter measured at 23° C. according to ASTM D256.

Abstract: An interfacial process for preparing a poly(aliphatic ester-carbonate) includes providing an initial polymerization reaction mixture comprising an aliphatic C6-20 dicarboxylic acid, a bisphenol, an alkali hydroxide, and optionally a catalyst in a solvent system comprising water and an immiscible organic solvent, adding an initial portion of a carbonyl dihalide over a first time period while maintaining the reaction at a first pH from 7 to 8; and adding a second portion of the carbonyl dihalide over a second, subsequent time period while maintaining the reaction pH at a second pH from 9 to 12, to provide a product polymerization mixture, wherein the amount of alkali hydroxide in the initial polymerization reaction mixture is effective to increase the fraction of the first time period at a measured pH of 7 to 8 compared to the same reaction mixture with a higher amount of alkali hydroxide in the initial polymerization mixture.
