A series of polydimethylsiloxane-polyphenolphlein tererpthalate multi-blook copolymer have been synthesized by using low temperature solution condensation tcchnique.Structure characterization of the block copolymers by IR, ¹H-NMR,viscosimetry,TEM etc. indicates that copolymers with controlled siloxane content can be obtained in high molecular weight.The copolymers can be either elastomeric or rigid depending on the siloxane block length and its content.The copolymers show two-phase morphology, good mechanical properties, thermostability and film formability.
