Abstract

There are provided:(i) a process for producing a thermoplastic elastomer composition, which comprises the step of feeding rubber and a thermoplastic resin through feed throats independent of one another, respectively, to an extruder to perform melt kneading thereof, wherein the feed throats are connected to the extruder; and(ii) a thermoplastic elastomer composition having a haze value of a glass plate of not higher than about 2%, provided that the haze value is measured with use of an apparatus according to regulations prescribed in ISO 6452 after a lapse of heating time of 20 hours at a heating temperature of 100° C.
