20 Feb 2004TL;DR: In this paper, a thermoplastic composition comprising a matrix of a polycarbonate polymer in which are embedded polysiloxane domains with an average domain size between 20 and 45 nanometers is presented.
Abstract: A thermoplastic composition comprising a matrix of a polycarbonate polymer in which are embedded polysiloxane domains with an average domain size between 20 and 45 nanometers. Said compositions can be obtained by combining a first polycarbonate/poly(diorganosiloxane) copolymer; with a second polycarbonate/poly(diorganosiloxane) copolymer. A range of translucencies are obtainable by varying the relative amounts of the two copolymers without substantial loss in impact properties.

TL;DR: In this paper, the authors synthesized six types of polycarbonates possessing glycidyl ethers (phenyl, tert-butyl, n -butyl and ethyl and isopropyl) and measured the ionic conductivity of their electrolytes including LiTFSI.

TL;DR: In this article, the fracture of a known ductile polymer (polycarbonate) is investigated and it is shown that polycarbonate obeys the Dugdale model of ductile yielding by comparing measured plastic-zone sizes and displacements to theoretical predictions.
Abstract: The fracture of a known ductile polymer (polycarbonate) is investigated. It is shown that polycarbonate obeys the Dugdale model of ductile yielding by comparing measured plastic-zone sizes and displacements to the theoretical predictions. Strain-energy release rates are calculated and the critical value is shown to be one or two orders of magnitude higher than critical values for brittle polymers.

TL;DR: In this paper, the formation of polymer-cyclodextrin inclusion compounds of polycarbonate (PC), poly(methylmethacrylate) (PMMA) and poly(vinylacetate) (PVAc) was successfully achieved.
