    摘要： A film that is both elastic and water-sensitive (e.g., water-soluble, water-dispersible, etc.) in that it loses its integrity over time in the presence of water is provided. To achieve these dual attributes, the film contains an olefinic elastomer and a water-soluble polymer. Although these polymers are normally chemically incompatible due to their different polarities, the present inventors have discovered that phase separation may be minimized by selectively controlling certain aspects of the film, such as the nature of the polyolefin, water-soluble polymer, and other film components, the relative amount of the film components, and so forth. For example, certain water-soluble polymers may be selected that have a low molecular weight and viscosity to enhance their melt compatibility with nonpolar polyolefins. This, in turn, may result in a film that is generally free of separate phases, which would otherwise limit the ability of the water-soluble polymer to contact water and disperse.

    摘要： An injection molding material that includes a renewable resin containing a combination of renewable polymers (e.g., starch and plant protein) and a plasticizer is provided. Although such compounds are normally difficult to process into thermoplastics, the present inventors have discovered that injection molding materials may nevertheless be formed by melt blending the renewable resin with a synthetic resin (e.g., polyolefin) while selectively controlling the nature of the resins and their relative concentrations. In this manner, a morphology may be achieved in which the renewable resin is present as a discontinuous phase that is dispersed within a continuous phase of the synthetic resin (e.g., “island-in-the-sea” morphology). The discontinuous and continuous phases may each constitute from about 30 vol. % to about 70 vol. %, and in some embodiments, from about 40 vol. % to about 60 vol. %. With such a morphology, the continuity of the synthetic resin can minimize the aggregate properties of the renewable resin such that the molding material possesses melt properties similar to that of the synthetic resin. Further, this morphology may also minimize the need to use different molding tools as the shrinkage properties of the overall composition may be substantially similar to that of the synthetic resin.

    摘要： A film that contains a thermoplastic polyurethane and water-soluble polymer is provided. The film is both elastic and water-sensitive (e.g., water-soluble, water -dispersible, etc.) in that it loses its integrity over time in the presence of water. The dual attributes of elasticity and water-sensitivity may be achieved by reducing the tendency of the thermoplastic polyurethane and water-soluble polymer to form separate phases. Namely, phase separation may cause the elastomer to act as a barrier and limit the ability of the water-soluble polymer to contact water and thereby disperse. To minimize such phase separation, a variety of aspects of the film construction may be selectively controlled, such as the nature of the thermoplastic polyurethane and water-soluble polymer, the relative amount of each component, and so forth. For example, thermoplastic polyurethanes are polar in nature and thus may be generally compatible with water-soluble polymers (e.g., polyvinyl alcohol), which are also polar in nature. Further, water-soluble polymers having a relatively low molecular weight and viscosity typically possess better melt compatibility with polar thermoplastic polyurethanes. By carefully controlling the nature of the polymers used to form the film, the present inventors have discovered that a film may be formed that is generally free of distinct phases.
