TRANSLUCENT THERMOPLASTIC COMPOSITION, METHOD FOR MAKING THE COMPOSITION AND ARTICLES MOLDED THERE FROM.

Document Type and Number:

WIPO Patent Application WO2004076541

Kind Code:

A3

Abstract:

A thermoplastic composition comprising a matrix of a polycarbonate polymer in which are embedded polysiloxane domains with an average domain size between 20 and 45 nanometers. Said compositions can be obtained by combining a first polycarbonate/poly(diorganosiloxane) copolymer; with a second polycarbonate/poly(diorganosiloxane) copolymer. A range of translucencies are obtainable by varying the relative amounts of the two copolymers without substantial loss in impact properties.
