摘要： 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).

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Composite blends of polyester containing plastic materials, and a starch-based polymeric material that increases the biodegradability of the polyesters of such a composite in simulated or actual marine conditions (e.g., simulated by ASTM D-6691). Enhanced rate or extent of biodegradation may also be exhibited in simulated or actual land-based disposal conditions. The starch-based polymeric materials are substantially amorphous, and are homogenously blended with the polyester plastic materials. While polyester plastics such as PBAT, PLA, PCL, and/or PBS may exhibit some biodegradability characteristics when composted and/or disposed of in landfill conditions at elevated temperatures, they exhibit limited if any biodegradability when disposed of in a marine environment. Even conventional blends of starch with such polyesters do not exhibit any significant marine biodegradability with respect to the polyester components therein. Third party testing shows the present blends exhibit substantially complete biodegradability of the entire composite under marine conditions, after about 400 days.
