Abstract
Polymer blends containing poly(phenylene sulfide) (PPS) and liquid cry stalline polymer (LCP) of varying compositions were injection molded a nd tested. Three-point bending tests were carried out on annealed and unannealed samples at various temperatures and strain rates. The time- temperature master curves were constructed by shifting the experimenta l modulus data at each point of the curves. The increase in bending mo dulus and reduction of bending strength with increasing LCP content we re attributed to the skin-core morphology. The time-temperature curves revealed that the bending modulus of the blends can be superimposed o ver a wide range of temperatures and strain rates.
