Key statement: Disclosed is a process for producing a thermoplastic elastomer composition having a matrix phase comprising a polyamide and an ethylene/ vinyl alcohol copolymer and a disperse phase comprising a rubber composition, by which gelation by a reaction between a polyamide and an ethylene/vinyl alcohol copolymer can be inhibited and the dispersion of the rubber composition can be good.
So we used the traditional method that was almost adopted to forecast the disperse phase morphology to calculate the shear rate with knowing the size of the dispersed phase in the molded parts.
In separate vessel, disperse phase D with mixing at room temperature.
This method does not depend on the number of the tracked particles which model the motion of the disperse phase, contrary to the Lagrangian approach, at which convergence is determined by the number of the tracked single particles that can be up to hundreds of thousands, and it requires high computational capabilities.
All of the models outlined in the book agree with the known results of DNS and LES of the continuous phase combined with Lagrangian trajectory simulation of the disperse phase.
The phase that is under the form of some fine drops is named the disperse phase or the internal phase.
Key statement: A rubber composition with disperse phase particles containing poly(phenylene ether) can be formed by a method that includes melt blending an uncured rubber with a poly(phenylene ether) composition containing a poly(phenylene ether) and an oil to form an uncured rubber composition, then curing the uncured rubber composition.
The use of ECO was also found to improve the fracture properties of the epoxy polymers, though no disperse phase was observed in this case, and the improvement of the toughness was ascribed to the lower crosslinking density of the modified networks.
On the other hand, the deformation of a disperse phase is retarded by a large interfacial tension, high dispersed phase viscosity, and a small droplet size.
Disperse phase 13 in phase A, add phase C and continue mixing
In immiscible systems, coalescence and breakup of the disperse phase is a collaboration of interfacial tension and viscoelastic properties of the blends (10).
Apart from the most important factors for homopolymers, such as orientation and crystallization phenomena, the mechanical properties of two-phase systems are also influenced, to a large extent, by the particle size and distribution in the disperse phase.
