LAYERED COMPOSITION HAVING MULTI-CHARGED ONIUM ION AS EXCHANGE ION, APPLICATION OF THE SAME COMPOSITION FOR PREPARING MONOMER, OLIGOMER AND POLYMER INTERCALATION MATERIAL AND NANO COMPOSITE PREPARED BY USING LAYERED COMPOSITION OF THE INTERCALATION MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an intercalation material capable of giving preferable properties such as the lowering of oxygen permeability to a matrix polymer. ;SOLUTION: A surface modified layered silicate material has multi-charged onium ion in place of plural interlayer anions on the surface of a platelet inside part by intercalation and contains a laminated layer of clay silicate platelets formed so that the interval between the adjacent layers of the layer materials is widened to at least about 3 , preferably at least to about 15 , usually at least up to 10 , preferably up to 15 and usually 15-20 , for example, up to 18 and the composite material contains the matrix polymer and the layer silicate material.;COPYRIGHT: (C)2000,JPO
