抄録

The orientation of kaolinite (Dixie clay) in SBR rubber which was vulcanized with an injection molding machine was determined by X-ray diffraction and electron microscope, and the relation between orientation degree of the kaolinite and compression set of the vulcanized rubber was discussed.<br>Following results were obtained:<br>1) Plane (001) of the kaolinite was orientated parallel to direction of flow of the rubber in the center of the vulcanized rubber, but it was orientated parallel to each surface on surface portion of the vulcanized rubber.<br>2) The compression set was decreased in proportion to the decrease of the orientation degree of the kaolinite.<br>Therefore, it is thought that physical properties of the vulcanized rubber is influenced by orientation degree of the kaolinite
