  • Publication number: 20140148534
    Abstract: A thermoplastic starch (TPS) comprises (in weight parts) 20-80 parts of starch, 5-40 parts of biodegradable polyester prepolymer, 0.01-10 parts of reaction activator, 0.01-1.0 part of catalytic deactivator, 0.01-1.0 part of antioxidant, and 5-50 parts of auxiliary agents. The said prepolymer has a molecular weight of 10,000-100,000 Daltons, a viscosity range of 0.30-1.2 dL/g, which is measured by Ubbelohde viscometer method, and a melting point range of 60-180° C. The terminal reactive group content of the prepolymer is 1.0-20.0 meq/Kg, which is measured by a terminal group titration process. A polyester/starch composite material comprising the TPS and its preparation method are also provided.

  • Publication number: 20100249361
    Abstract: There is disclosed a process for producing a polyester copolymer. The process comprises the step of condensating a hydroxyacid, a diol, a dicarboxylic acid and a functionalizing agent selected to form a prepolymer having a polyester copolymer backbone with arms comprising cross-linkable groups extending therefrom. The process also comprises the step of coupling said prepolymer in the presence of a coupling agent to cross link the arms of plural prepolymer backbones and thereby form said polyester copolymer comprising said plural straight chain polyester copolymers coupled to each other by said cross-linked arms. The polyester copolymer may be biodegradable and may be used as a modifier to increase the strength of polylactic acid.
