    摘要: A thermoplastic material composition containing certain biodegradable and renewable components is described. The thermoplastic composition that includes a least one kind of algae or a blend of at least one kind of algae and a plant polymer a blend of algae and/or plant-based polymers, such as proteins and starches, as relatively low cost feedstock. The algae or blend may be plasticized. Additionally, a method adapted for large scale fabrication of fibers, films, or extruded articles is also described.

    摘要: A thermoplastic starch for use in a melt-processed composition (e.g., fiber, nonwoven web, etc.) is provided. The thermoplastic starch contains an enzymatically debranched starch and a plasticizer. By selectively controlling certain parameters of the enzymatic modification process (e.g., temperature, enzyme and starch concentrations, reaction time, isolation method, etc.), the present inventors have discovered that a native starch may be hydrolyzed in a highly efficient manner to form compositions having a comparably lower weight average molecular weight and viscosity, which are particularly suitable for use in the formation of thermoplastic starches for use in melt processing applications.

    摘要: A film that is formed from a biodegradable polymer blend of different aliphatic-aromatic copolyesters is provided. More specifically, the blend contains a first copolyester formed from a terephthalic acid monomer. The use of a terephthalic acid monomer results in a polymer chain containing 1,4-(para-) terephthalate units linked in a generally linear configuration (e.g., ˜180°). The blend also contains a second aliphatic-aromatic copolyester formed from a phthalic acid and/or isophthalic acid monomer. The use of such a monomer results in a polymer chain containing 1,2-(ortho-) and/or 1,3-(meta-) linked units. The inclusion of 1,2-(ortho-) and/or 1,3-(meta-) linked units into the polymer backbone of the second copolyester introduces an angle or “kink” (e.g., ˜120° kink for a 1,3-linkage) into the otherwise linear polymer chain. The “kinks” in the second copolyester backbone reduce its melting point and degree of crystallinity, which have an influence on its physical properties (e.g., toughness, tensile strength, and crystallization rate). Thus, the physical properties of the second copolyester may differ substantially from those of the first copolyester. In this regard, the “kinked” second copolyester can provide flexibility for forming films with a wide range of properties that is superior to that which may be achieved using either of copolyesters alone.

    摘要: A film that is biodegradable 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. The film contains a biodegradable polyester, starch, water-soluble polymer, and plasticizer. The desired water-sensitive attributes of film may be achieved in the present invention by selectively controlling a variety of aspects of the film construction, such as the nature of the components employed, the relative amount of each component, the manner in which the film is formed, and so forth.
