Impact modified blends of polypropylene (PP) and a commercial polyolefinic elastomer (POE) were prepared and further reinforced with suitable nanoclay. The addition of elastomer and nanoclay improved the impact properties significantly, whereas moderate improvement was observed in tensile strength, flexural strength, flexural modulus, and elongation at break. The heat distortion temperatures of the filled compositions were close to that of neat PP. The compositions exhibited excellent flow characteristics. Blending sequence between PP, POE and Nanoclay was altered and its effect on the properties of Nanocomposite was investigated. The preferential migration of the blend components leading to different intercalated morphology was reported. © Central Institute of Plastics Engineering & Technology 2010. Source

Hysteresis characteristics of high modulus low shrinkage (HMLS) polyester tire yarn and cord were evaluated to determine "specific work loss," which indicate its heat generation characteristics. Test parameters were selectively chosen, considering the service conditions of high-speed passenger radial tires in which HMLS polyester tire cords are predominantly used. Specific work loss was found to increase exponentially with the increase in extent of stress relief. Dynamic property of this yarn and cord was also studied to determine "loss tangent (tan δ)," which influences rolling resistance of tires in service. A good correlation has been found between specific work loss of hysteresis test (a slow speed test) and tan δ of dynamic test (a high-speed test). Dynamic property of polyester dipped cord was investigated for a wide range of temperatures (100-180 °C) and frequencies (5-25 Hz). Tan δ at 100 °C was found to be relatively low and its magnitude remained at the same level for a wide range of frequencies. This is a favorable condition for the high-speed passenger radial tires, made out of HMLS polyester tire yarn. Microstructure of HMLS polyester yarn was analyzed. Crystallinity is around 43% (measured by Wide angle x-ray scattering); crystal width and long period are 61 and 142 A•, respectively. Source
