COMPOSITIONS AND METHODS FOR DELIVERING AN AGENT TO A WOUND
The invention provides compositions featuring chitosan and polyethylene glycol and methods for using such compositions for the local delivery of biologically active agents to an open fracture, complex wound or other site of infection. Advantageously, the chitosan-PEG compositions can be loaded with one or more antimicrobial agents, including hydrophobic agents, and can be tailored to the needs of particular patients at the point of care (e.g., in a surgical suite, clinic, physician's office, or other clinical setting).
Novel Hydrogels
Hydrogels are based on the reaction of thiols with electron-deficient heteroaromatics. This reaction can take place under physiological conditions and is thus suitable for the encapsulation of cells.
Foam formulations
Embodiments of the present disclosure are directed towards foam formulations that include a high functionality polyether polyol, an aromatic polyether polyol, an amine initiated aliphatic polyether polyol, and a diol.
POLYETHER BLOCK AMIDE-POLY(METH)ACRYLATE FOAMS
A mixture contains at least one amino-regulated polyether block amide (PEBA) and at least one poly(meth)acrylate selected from poly(meth)acrylimides, polyalkyl(meth)acrylates, and mixtures thereof. The mass ratio of PEBA to poly(meth)acrylate is 95:5 to 60:40. The polyalkyl(meth)acrylate contains 80% by weight to 99% by weight of methyl methacrylate (MMA) units and 1% by weight to 20% by weight of C1-C10-alkyl acrylate units, based on the total weight of polyalkyl(meth)acrylate. The mixture can be processed to give foamed mouldings. The mouldings can be used in footwear soles, stud material, insulation or insulating material, damping components, lightweight components, or in a sandwich structure.
Delivery systems based on hydrogel compositions and methods thereof
The invention provides a novel, versatile degradable hydrogel composition, and methods thereof, with precisely tunable stiffness, plasticity (e.g., degree of covalent vs. physical crosslinks) and predictive disintegration rates degradation, allowing controlled disintegration and release of therapeutic cells or pharmaceuticals and/or in vitro 3D cell expansion.
METHODS OF MANUFACTURING ARTICLES UTILIZING FOAM PARTICLES
Methods for manufacturing articles, including articles of footwear, apparel, and sporting equipment are provided. The methods comprise decorating a plurality of foam particles. The decorating can comprise applying a coating on the foam particles, or embossing or debossing the foam particles, or both. The decorating can comprise applying a coating on the foam particles by printing, painting, dyeing, applying a film, or any combination thereof. The plurality of foam particles are affixed utilizing aspects of additive manufacturing methods. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
PLANT-DERIVED POLYAMIDE-BASED ELASTOMER FOAM MOLDED BODY, METHOD FOR MANUFACTURING SAME, AND FOAM PARTICLES THEREOF
Since most elastomer foam molded bodies use a petroleum-derived resin as a base resin, there is a demand for an elastomer foam molded body with high rebound resilience and low environmental load. An object of the present invention is to provide a foam molded body having a rebound resilience coefficient equivalent to that of a petroleum-derived polyamide-based elastomer foam molded body, and excellent moldability during in-mold foaming; foam particles; and a method for producing the foam molded body.
The present invention relates to a polyamide-based elastomer foam molded body comprising 50 to 100 mass % of a block copolymer resin containing a polyamide block as a hard segment and a polyether block as a soft segment, wherein the copolymer resin has a biobased product content as measured by ASTM D6866 of 30% or more.
Moisture Curable Adhesive Compositions
A moisture curable composition, a method of applying the same, and a composition including the same are disclosed herein. In some embodiments, a curable composition, comprises: a component (A) having an organic polymer containing reactive silicon groups represented by the following general formula (1): —Si(R.sup.1.sub.3-a)X.sub.a (1) wherein R.sup.1 represents an alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, or an aralkyl group having 7 to 20 carbon atoms, wherein X represents a hydrolyzable group, wherein each X is the same or different when two or more X are present, a is an integer from 1 to 3, when a is 1, each R.sup.1 may be the same or different, and when a is 2 or 3, each X may be the same or different; a component (B) having a chlorinated polyolefin polymer; and a component (C) having a carboxylic acid metal salt.
