The mechanical strength of the blends was deteriorated with increasing phosphinate-based flame retardant content while the tensile modulus increased. For UL94V test, the addition of approximate to 10wt% phosphinate did not have a significant effect on the flame retardancy showing V2 grade while further addition gave rise to char formation resulting in V0 grade. Limiting oxygen index values increased greatly by ca. 34% at 5wt% phosphinate, followed by mild increase by further addition. Heat release rate peaks of the blends were reduced and broadened with increasing phosphinate content showing little difference from 15wt%. The complex viscosity increased with phosphinate content, but its increasing extent decreased at a high frequency. In the Cole-Cole plot, the presence of the phosphinate shifted the plot from unfilled blends without showing a single master curve depending on its loading level.
