Abstract: A method for producing zeolite embedded polyolefin films for packaging polyurethane foams also embedded with zeolite.

Abstract: The invention includes chitosan nanofibers having enhanced structural integrity, compositions comprising such chitosan nanofibers, and related methods of use. In a particular aspect, electrospun chitosan nanofibers can be reversibly acylated to enhance structural integrity and promote healing and the formation of tissues in a subject. In another aspect, electrospun chitosan nanofibers comprising at least a portion of the amino groups protected, such as through N-tert-butoxycarbonyl groups, demonstrate enhanced structural integrity and promote healing and the formation of tissues in a subject. The invention also includes compositions and methods for producing a modified chitosan material having anti-inflammatory and pro-healing characteristics and methods of using the modified chitosan materials in a film, a gel, a membrane, microfibers, nanofibers, nano- or micro-particles/spheres and/or sponges. In some aspects, microspheres and methods of producing microspheres comprising modified chitosan are included.

Abstract: A method for preparing low odor polyurethane foams by the use of a high silica zeolite and a foam-forming composition.

Abstract: Provided are films made from polymer blends including post-consumer resin (PCR). The films are formed from a polymer blend that includes a PCR, a low density polyethylene and/or ethylene/carbon monoxide copolymer (ECO copolymer), and a modification agent. The films, which include a PCR, contribute to improved sustainability and in aspects maintain or minimize the reduction of desirable properties, such as elastic recovery.
