    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 μm, or less than 1 μm) 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.

    Abstract: Described herein are methods for rendering biodegradable a plastic material that is not itself biodegradable, by blending the plastic material with a carbohydrate-based polymeric material that is formed from one or more starches, and a plasticizer (e.g., glycerin). The carbohydrate-based polymeric material is less crystalline than the starting starch materials, e.g., being substantially amorphous, and having a crystallinity of no more than 20%. Third party testing shows blends of such materials render the entire blend biodegradable, believed to be due to the low crystalline substantially amorphous carbohydrate-based polymeric material breaking the hygroscopic barrier associated with the non-biodegradable plastic material, so that when blended together, both the plastic material and the carbohydrate-based polymeric material are biodegradable.

    Abstract: Thermoplastic starch-based materials formed as a reactive extrusion product from one or more starches, plasticizers, with the addition of a diacid, diglycidyl ether, silicone and/or a glyceride additive added during gelatinization of the starch and plasticizer, before blending of such starch-based polymeric material with any other polymer (e.g., polyester biopolymers, polyolefins, polyamides, etc.). Silicones, where added, may alternatively be added after formation of the thermoplastic starch, e.g., as part of a masterbatch, when blending with another polymer. Addition of silicone reduces glycerin migration and smoke generation, particularly when processing such compositions to form nonwovens. Addition of glycerides (e.g., triglycerides) can increase hydrophobicity of the resulting starch-based polymeric material. Addition of the diacid can reduce molecular weight, while diglycidyl ether addition can build such molecular weight back up, resulting in a narrower molecular weight distribution, and improved processability of the resulting starch-based polymeric material, particularly for nonwoven applications.

    Abstract: Composite blends of PBAT (or another similar polyester) with PLA and a carbohydrate-based polymeric material. While PLA is not compostable under home composting conditions (e.g., temperature of 28° C.) on its own, when blended in the manner described herein, it is compositable under such conditions. The addition of the PLA increases the rigidity of the composite blend, as PBAT on its own is so flexible as to be problematic for use in carryout bags, and the like. An exemplary blend may include 30-55% by weight of the carbohydrate-based polymeric material, up to 20%, or up to 15% by weight of PLA, with the balance of polymeric content being PBAT (e.g., 30-60% PBAT). Other components (e.g., an inorganic filler, such as calcium carbonate) may also be included in the blend.
