Abstract
BisphenolโA polycarbonate (PC) and polystyrene (PS) were meltโblended and molded for dynamic mechanical tests on a Dynastat. Corresponding powders were submitted to thermal analysis using the differential scanning calorimeter. The deduced glass transition temperatures of the blends and those of the pure polymers were compared to estimate the miscibility of the two polymers.

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 รeld of polymer blends and alloys. The methods for preparing PCรPS copolymers are difficult and comp
Polycarbonate (PC)/polystyrene (PS) blend is a typical immiscible system. It is, however, still transparent. In this paper, this irregular phenomenon is clariรed experimentally and theoretically.

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
