PRODUCTION METHOD OF FILLER-DISPERSED MELT-KNEADED PRODUCT, MOLDED RESIN PRODUCT OBTAINED BY PRODUCTION METHOD OF MELT-KNEADED PRODUCT, AND PRODUCTION METHOD OR USE THEREOF

摘要

PPROBLEM TO BE SOLVED: To provide a melt-kneaded product of an incompatible polymer blend with a controlled co-continuous structural composition from an incompatible polymer blend, to provide a molded resin product of an incompatible polymer blend with a controlled co-continuous structural composition from the melt-kneaded product, and to provide a material obtained by subjecting the molded resin product to solvent treatment. PSOLUTION: The melt-kneaded product is obtained in such a manner that a melt-kneaded resin or elastomer obtained by treating a filler, an incompatible resin or the like in specified ratios under the conditions where the speed of rotation of a screw is 600 rpm to 3,000 rpm and its shear rate is 900 to 4,500 secSP-1/SPis sent from a rear end of the screw to its front end, then the melt-kneaded resin or elastomer is subjected to circulation where the melt-kneaded resin or elastomer is trapped in a space at the front screw, and then moved to the rear screw end, the co-continuous structure as the internal structure of the melt-kneaded product is controlled, and the size of the continuous phase is freely changed at mesoscopic level (0.3 to 100 m). The molded resin product, and the material obtained by subjecting the molded resin product to solvent treatment are also provided. PCOPYRIGHT: (C)2009,JPO&INPIT
