Thermoplastic film, thermoplastic resin composition, and phyllosilicate

Abstract

There is provided a film comprising a layered silicate cation-exchanged with an organic cation and a polyester or polycarbonate. The organic cation is represented by the following formula (I): (R)n-L+  (I) wherein R is a group represented by the following formula (I-1): wherein R1 is a divalent hydrocarbon group having 5 to 20 carbon atoms, and R2 is a divalent hydrocarbon group having 1 to 20 carbon atoms, an alkyl group, an aryl group or an aralkyl group, L+ is an ammonium ion, a phosphonium ion or a hetero aromatic ion, and n is an integer of 1 to 4, with the proviso that when L+ is an ammonium ion or a phosphonium ion, n is 4 and four Rs may be the same or different. This film has the layered silicate highly dispersed therein and is excellent in various properties such as mechanical properties and dimensional stability.
