  • Patent number: 11926929
    Abstract: Described are very high molecular weight (e.g., over 2 million, such as 3-20 million g/mol) starch-based materials, and formulations including such, which can be spun in spunbond, melt blown, yarn, or similar processes. Even with such very high molecular weights, the formulations can be processed at commercial line speeds, with spinneret shear viscosities of 1000 sec?1, without onset of melt flow instability. The starch-based material can be blended with one or more thermoplastic materials having higher melt flow index value(s), which serve as a diluent and plasticizer, allowing the very viscous starch-based component to be spun under such conditions. The particular melt flow index characteristics of the thermoplastic diluent material can be selected based on what type of process is being used (e.g., spunbond, melt blown, yarn, etc.). The starch-based material may exhibit high shear sensitivity, strain hardening behavior, and/or very high critical shear stress (e.g., at least 125 kPa).

  • Patent number: 11674014
    Abstract: Described herein are blends of starch or starch-based materials with polymeric materials, where the starch or starch-based material is intimately blended with the polymeric material, so as to exhibit very small particles sizes (e.g., less than 2 ?m, or less than 1 ?m) for the starch or starch-based material in the matrix of the polymeric material. Such intimate dispersion of very small particles provides for far more of the particles dispersed more evenly throughout the matrix of the polymeric material, which may enhance various performance characteristics of the blended composite material. Methods of producing articles from such blends exhibiting such small particles and excellent dispersion are also disclosed.

  • Patent number: 11674018
    Abstract: Described herein are blends of carbohydrate-based polymeric materials with other polymeric materials, where the carbohydrate-based polymeric material is intimately blended with the other polymeric material, so as to exhibit very small particles sizes (e.g., less than 2 ?m, or less than 1 ?m) for the carbohydrate-based polymeric material in the matrix of the other polymeric material. Such intimate dispersion of very small particles provides for far more of the particles dispersed more evenly throughout the matrix of the other polymeric material, which may enhance various performance characteristics of the blended composite material, and provide for more consistent achievement of such characteristics, from batch to batch. Methods of producing articles from such blends exhibiting such small particles and excellent dispersion are also disclosed. While suitable for use in a wide variety of fields, examples may include for the coating of paper cups, and as a capsule material for sustained release fertilizer.

  • Publication number: 20220227949
    Abstract: Described herein are starch-based materials, and formulations including such for use in directional alignment extrusion processes. The present compositions exhibit critical shear stress characteristics that allow extrusion at high shear rates and line speeds, without onset of melt flow instability. The present compositions provide sufficient melt strength to allow such compositions to be directionally oriented by stretching the heated polymer (e.g., the polymer melt) following initial extrusion, directionally aligning the molecular chains of the heated polymer blend in the machine-direction, the cross-direction, or both. In an embodiment, the starch-based material is blended with one or more thermoplastic materials having desired melt flow index value(s), which serves as a diluent, allowing the very viscous starch-based component to be processed under such conditions.
