โœฆ Synopsis

A radiation grafted copolymer of polycarbonate (PC) and polystyrene (PS) was used as a compatibilizer of PC/PS melt blends. The compatibility and morphology of PC/PS/PC-g-PS blends were studied by di โ€ erential scanning calorimetry and scanning electron microscopy. As a consequence of the addition of PC-g-PS, the compatibility of PC/PS blends was improved ; the dimensions of the dispersed phases and the interfacial tension between the two phases were reduced. Additionally, stabilization against gross segregation and interfacial adhesion of the blends were also improved by adding PC-g-PS as a compatibilizer.

Polycarbonate (PC)/polystyrene (PS) blend is a typical immiscible system. It is, however, still transparent. In this paper, this irregular phenomenon is clariรed experimentally and theoretically. A new method of obtaining birefringence-free polymers without sacriรcing orientation in materials is pro

Polycarbonate (PC)/polystyrene (PS) blend is an immiscible system. The use of copolymers as compatibilizers in blends of immiscible polymers is one approach which is being developed within the larger รeld of polymer blends and alloys. The methods for preparing PCรˆPS copolymers are difficult and comp

## Abstract The influences of different molecular sizes and contents of bisphenol A polycarbonate (PC) on the miscibility, morphology, and physical properties of a polystyrene/PC (PS/PC) molecular composite are examined. The polymerization of the matrix monomer, styrene, which is completely miscibl
