POLYESTER-BASED THERMOPLASTIC COMPOSITION, PRODUCTION METHOD AND HOLLOW BODIES MADE OF SAID COMPOSITIONS

摘要

The present invention relates to a polyester-based thermoplastic composition which may be used for the manufacture of hollow bodies such as bottles, films and sheets, especially for packaging. It relates more particularly to a polyester-based thermoplastic composition and to films, hollow bodies or bottles obtained by forming this composition and having improved gas barrier and mechanical properties. The polyester composition comprises a mineral filler composed of a metal phosphate of a tetravalent metal, dispersed in the form of particles having a thickness of less than 40 nm. The compositions of the invention make it possible to obtain formed articles such as films or transparent preforms.
