20110135901 | Polysulfone and poly(N-vinyl lactam) polymer alloy and fiber and filter materials made of the alloy - A polymer alloy has been developed comprising a polysulfone and a vinyl lactam polymer. The resulting alloy has excellent thermal characteristics and even in the presence of substantial quantities in vinyl lactam polymers, has solvent resistance to both organic and aqueous solvent materials. The materials, when dissolved in solvents, can be spun from a variety of solvents into a variety of useful fiber materials. The resulting fine fiber, microfiber and nanofiber materials have excellent thermal and chemical resistance for a variety of fiber applications. The polymer alloys of the invention can be spun into nanofiber mats that can act as a filtration media and can also be combined into conventional substrate materials for fabrication into filter structures. | 06-09-2011 |
20110226690 | POLYMER BLEND, POLYMER SOLUTION COMPOSITION AND FIBERS SPUN FROM THE POLYMER BLEND AND FILTRATION APPLICATIONS THEREOF - The invention relates to a web or filter structure such as the filtration media comprising a collection of fiber comprising a first polymer and a second polymer in a fine fiber or fine fiber web structure. The combination of two polymers provides improved fiber rheology in that the fiber has excellent temperature and mechanical stability. The combination of polymers imparts the properties of elasticity or tackiness, which is desirable for adhering particles to the fiber web, with high temperature resistance. | 09-22-2011 |
