Abstract:
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. In the process, the polyamide resin and the rubber composition are melt-blended to the extent necessary for the rubber composition to form a disperse phase, and then the ethylene/vinyl alcohol copolymer is added and further melt-blended together.
