Zusammenfassung:	PROBLEM TO BE SOLVED: To produce an impact-resistant thermoplastic resin composed of a wet elastomer component and a fragile thermoplastic polymer in an industrially simple manner by one treatment process if possible. SOLUTION: An elastomer component A is supplied to a twin-screw extruder formed from a distribution section, a crushing section, a, section supplying a thermoplastic polymer B to the extruder, a section equipped with a mixing element, a kneading element and/or a separate plasticizing element, a degassing section and a feed-out zone in a feed direction and equipped with screws rotated in the same way and the water discharged from a dehydration opening is allowed to be present as a liquid phase partially or wholly. Therefore, the residual water contained in rubber partially dehydrated at first is already removed as water in the first crushing section and the feed amt. of rubber is 3-8wt.% of the amt. of the wet rubber in the first crushing section and below 1wt.% in a second crushing section.
