20140262016 | Hot Melt and Pressure-Sensitive Adhesives that Include Highly-Plasticized Cellulose Esters and Methods and Articles Relating Thereto - Hot melt and pressure-sensitive adhesives may comprise highly-plasticized cellulose esters, e.g., a cellulose ester and a plasticizer, the plasticizer included in an amount of about 30% to about 60% by weight of the cellulose ester. A highly-plasticized cellulose ester adhesive that is non-tacky at room temperature may be utilized by heating an adhesive to yield an adhesive melt, the adhesive comprising a cellulose ester and a plasticizer, the plasticizer included in an amount of about 15% to about 60% by weight of the adhesive; applying the adhesive melt to a first surface; and adhering a second surface to the first surface with the adhesive. | 09-18-2014 |
20140262017 | Hot Melt and Pressure Sensitive Adhesives that Include Highly-Plasticized Cellulose Esters and Methods and Articles Relating Thereto - Hot melt and pressure-sensitive adhesives may comprise highly-plasticized cellulose esters, e.g., a cellulose ester and a plasticizer, the plasticizer included in an amount of about 30% to about 60% by weight of the cellulose ester. A highly-plasticized cellulose ester adhesive that is tacky at room temperature may be utilized by applying the adhesive to a first surface; and adhering a second surface to the first surface with the adhesive. | 09-18-2014 |
20140262018 | Hot Melt and Pressure Sensitive Adhesives that Include Highly-Plasticized Cellulose Esters and Methods and Articles Relating Thereto - Hot melt and pressure-sensitive adhesives may comprise highly-plasticized cellulose esters, e.g., a cellulose ester and a plasticizer, the plasticizer included in an amount of about 30% to about 60% by weight of the adhesive. A highly-plasticized cellulose ester adhesive may be utilized in a sheet form by disposing the adhesive sheet between a first surface and a second surface; and heating the adhesive sheet so as to adhere the first surface to the second surface. | 09-18-2014 |
20140272131 | Hot Melt and Pressure Sensitive Adhesives that Include Highly-Plasticized Cellulose Esters and Methods and Articles Relating Thereto - Highly-plasticized cellulose esters may be useful as adhesives, including for use in producing laminates. For example, producing a laminate may include providing an adhesive melt that comprises an adhesive that comprises a cellulose ester and a plasticizer, the plasticizer included in an amount of about 30% to about 75% by weight of the adhesive; applying the adhesive melt to a substrate; and allowing the adhesive melt to cool so as to yield a laminate on the substrate. | 09-18-2014 |
20140275516 | NATURALLY DERIVED MIXED CELLULOSE ESTERS AND METHODS RELATING THERETO - Mixed cellulose esters derived from natural products (e.g., natural cellulose esters) may be produced by methods that include acylating a cellulose with a natural esterification reactant or a derivative thereof to yield a natural cellulose ester. In some instances, the natural esterification reactant derivative may be a saponified natural esterification reactant. In some instances, the natural cellulose esters may have a glass transition temperature of about −55° C. to about 170° C. | 09-18-2014 |
20150090156 | ADHESIVES THAT INCLUDE PLASTICIZED STARCH DERIVATIVES AND METHODS AND ARTICLES RELATING THERETO - The adhesive compositions that include starch derivatives, plasticizers, optionally cellulose derivatives, and optionally other additives. By tailoring the composition and concentration of these components, hot melt adhesive compositions, hot melt pressure sensitive adhesive compositions, and pressure sensitive adhesives have been produced. Further, these adhesive compositions may be useful in articles including diapers, laminates, repositionable advertisements, and many more. | 04-02-2015 |
20150306230 | DRUG DELIVERY VEHICLES COMPRISING CELLULOSE DERIVATIVES, STARCH DERIVATIVES, AND COMBINATIONS THEREOF - A drug delivery vehicle (e.g., a patch, a pill, an intravaginal ring, and an implant) may include a polymer matrix comprising a plasticizer and at least one selected from the group consisting of: a cellulose ester, a cellulose ether, a starch ester, a starch ether, and a combination thereof. A drug may be dispersed in the polymer matrix, in another portion of the drug delivery vehicle, or both. | 10-29-2015 |
20150307754 | ADHESIVES THAT INCLUDE HIGHLY-PLASTICIZED CELLULOSE ESTERS AND METHODS AND ARTICLES RELATING THERETO - Adhesives may include a base polymer composition, optionally a tackifying resin, optionally a wax, and optionally additives (e.g., plasticizers, fillers, antioxidants, and the like, and combinations thereof), where the base polymer comprises a highly plasticized cellulose ester and optionally polymers traditionally used in pressure sensitive adhesives, hot melt pressure sensitive adhesives, or hot melt adhesives (e.g., ethylene vinyl acetate copolymers, polysiloxanes, and polyurethanes). | 10-29-2015 |
