5), the viscosity ratio of PA66/PPO blends was found to be higher than 4 at the shear rates of 100/s during extrusion, indicating that the reduction in particle size in PA66/PPO blends was largely caused by the extensional effect in TTSE.
Table 2 lists the mechanical properties, volume average particle diameters, and PSD index U of PA66/PPO blends extruded by TTSE and TSE.
The notched impact strengths of PA66/ PPO/PPO-g-MA blends extruded by TTSE and TSE are shown in Fig.
The tensile strengths and flexural strengths of PA66/PPO/ PPO-g-MA blends extruded by TTSE and TSE are shown in Figs.
This phenomenon was attributed to the finer morphology and stronger interfacial adhesion of blends extruded by TTSE than those of blends extruded by TSE.

2) The proportions of cross-listed securities on the BSE, the TTSE and the JSE are 33%, 40% and 26%, respectively.
The 3D flow field of TTSE was simulated in 13 process conditions.
A triangle-arranged TTSE connected with a melt pump system was self-made.
Noticeably, a melt pump between the extruder head and TTSE was used to keep [p.
After the TTSE was operating normally, 3 g of CaC'03 as a tracer was added into the feed inlet.
The axial pressure difference and RTD of TTSE were measured by numerical simulation and experiments at different inlet flow rates, screw speeds and screw configurations.
