Abstract

Blending of conventional polymers can be a convenient way of developing materials with novel or selectively enhanced properties which are possibly superior to those of the component [1]. This technique is far less costly and time consuming than the development of new polymers. Nevertheless, blends offer the possibility of tailor-making products to meet specific end needs. Therefore, blends are economically attractive and are experiencing significant growth [2]. Acrylonitrile-butadiene-styrene (ABS) is a widely used thermoplastics. Within the compositions of ABS, acrylonitrile (A) causes an improvement in chemical resistance and weatherability, butadiene (B) has the character of rubber toughness, and styrene (S) offers glossiness and processability. The relationships of the various components can be controlled to meet the requirements of a variety of applications. However, the overall mechanical properties of ABS are lower than those of most engineering plastics, and the heat distortion temperature of general grades of ABS is lower than 100°C [3,4]. In order to upgrade the use of ABS, one simple way is to blend ABS resin with other high performance engineering plastics such as polycarbonate (PC). Blends of PC and ABS have been commercially available for a number of years. PC can offer variation improvements in some properties, such as strength, dimensional stability, heat distortion temperature and impact resistance. In a typical ABS/PC blend, PC contributes toughness, matrix ductility and high temperature strength. At the mean time, ABS provides processing advantages and increased impact resistance particularly at low temperature rigorous engineering applications besides providing cost reduction with respect to PC. The objective of this research is to determine the mechanical properties (flexural, tensile, impact and creep) of super high impact ABS/PC blend at various blend compositions.
