    摘要: A breathable film formed from a thermoplastic composition that contains a rigid renewable polyester and has a voided structure is provided. To achieve such a structure, a thermoplastic composition that contains a renewable polyester and polymeric toughening additive is extruded onto a surface to form a precursor film in which the toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. The precursor film is thereafter stretched or drawn at a temperature below the glass transition temperature of the polyester (i.e., “cold drawn”). Without intending to be limited by theory, the present inventors believe that the deformation force and elongational strain of the drawing process causes debonding to occur in the renewable polyester matrix at those areas located adjacent to the discrete domains. This creates a network of voids located adjacent to the discrete domains.

    摘要: A melt-processed protein composition formed from a protein, plasticizer, and an electrophilic reagent is provided. The electrophilic reagent, for instance, may be selected to undergo a nucleophilic addition reaction with free sulfhydryl and/or thiyl radicals to help minimize the formation of disulfide crosslinking bonds that could otherwise lead to protein aggregation during melt processing. To enhance the degree to which the electrophilic reagent can limit crosslinking, a plasticizer is also employed that helps to mediate the adsorption of the electrophilic reagent into the internal structure of the protein, where it can be more stably retained. Furthermore, the temperature and shear rate employed during melt blending may also be selected to be relatively low to help limit polypeptide dissociation, thereby minimizing the impact of aggregation and embrittlement.

    摘要: A thermoplastic composition that contains a rigid renewable polyester and has a voided structure and low density is provided. To achieve such a structure, the renewable polyester is blended with a polymeric toughening additive to form a precursor material in which the toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. The precursor material is thereafter stretched or drawn at a temperature below the glass transition temperature of the polyester (i.e., “cold drawn”). This creates a network of voids located adjacent to the discrete domains, which as a result of their proximal location, can form a bridge between the boundaries of the voids and act as internal structural “hinges” that help stabilize the network and increase its ability to dissipate energy. The present inventors have also discovered that the voids can be distributed in a substantially homogeneous fashion throughout the composition.
