Abstract
A composition made from a transparent polysiloxane-polycarbonate copolymer and styrene-acrylonitrile copolymer (SAN) and, optionally, polycarbonate, the composition being transparent. A thin-walled article may be made from such a composition. A transparent composition made by combining a transparent polysiloxane-polycarbonate copolymer with styrene-acrylonitrile copolymer (SAN) and, optionally, polycarbonate, to produce a transparent composition. An article made by forming a transparent composition comprising a transparent polysiloxane-polycarbonate copolymer, styrene-acrylonitrile copolymer (SAN) and, optionally, polycarbonate into an article.
