RESIN COMPOSITIONS AND PROCESS FOR PRODUCING THE SAME

摘要

Resin compositions containing polycarbonate, polyarylate or a thermoplastic polyester resin with a silane-treated foliated phyllosilicate. The silane-treated foliated phyllosilicate is prepared by introducing into a swellable silicate a silane compound represented by the following general formula (1): YnSiX4-n, wherein n is an integer of 0 to 3; Y is optionally substituted C1-25 hydrocarbon group; and X is a hydrolyzable group or hydroxy, provided that n Y's and (4-n) X's are the same or different. These resin compositions satisfy at least one of the following conditions: (a) the silane-treated foliated phyllosilicate has an average layer thickness of 500 ANGSTROM or less; and (b) the ÄNÜ value is 30 or more and the average aspect ratio is from 10 to 300. In case of polyester resin compositions, definite conditions on rheological properties represented by eta e-3 eta , DELTA eta e and Je0 eta 0 are to be satisfied too.
