The thermoplastic resin composition comprising a thermoplastic resin composite clay intercalation compound, the interlayer clay complex compounds and their preparation are

摘要

PROBLEM TO BE SOLVED: To improve the rheological properties of a solvent by using a composite clay containing a surface-treating agent bonded to one or more lamellar silicates selected from smectite-group, vermiculite-group and kaolin-group clay minerals through covalent bond and having an average interlaminar thickness of smaller than a specific level in combination with a dispersion stabilizer. ;SOLUTION: This intercalation composite clay compound is composed of a composite clay containing 0.1-200 pts.wt. of a silanebased surface-treating agent bonded to 100 pts.wt. of one or more lamellar silicates selected from smectite-group, vermiculite-group and kaolin-group clay minerals through covalent bond and having an average interlaminar thickness of 200 in combination with 0.1-60 pts.wt. of a dispersion stabilizer. The dispersion stabilizer is e.g. a compound having polysiloxane chain as the main chain such as a silicone-based surfactant or a compound having polyether chain as the main chain such as polyethylene glycol. The objective thermoplastic resin composition is produced by compounding 100 pts.wt. of a thermoplastic resin such as polyamide resin or polycarbonate resin with 0.1-400 pts.wt. of the intercalation composite clay compound.;COPYRIGHT: (C)1998,JPO
