摘要： A new class of cost-effective carbon fiber precursors that comprise both hydrocarbon polymer and Pitch structural features in the same polymer structure to exhibit complementary advantages of both PAN- and Pitch-based carbon fiber precursors. The new class of carbon fiber precursors comprise a polymeric pitch copolymer, wherein the polymeric pitch copolymer includes a polymer chain and several pitch polycyclic aromatic hydrocarbon (PAH) molecules grafted or chemically bonded to the polymer chain. Method and processes for the creation of the new class of carbon fiber precursors are also presented, wherein said methods may comprise a thermally-induced coupling and extrusion step.

摘要： The present invention relates to a process for the preparation of polyolefin fibers having mean fiber diameters of less than 5000 nm, comprising the steps of: a) preparing a polyolefin solution in a solvent, b) placing said polyolefin solution in a fiber producing device comprising a body configured to receive said polyolefin solution, said body comprising one or more openings, and c) rotating the fiber producing device, wherein rotation of the fiber producing device causes the polyolefin solution to be passed through said one or more openings to produce polyolefin fibers having mean fiber diameters of less than 5000 nm, wherein said polyolefin is selected from the group comprising polyethylene polymers and copolymers having a weight average molecular weight Mw of at least 40 000 daltons, and polypropylene polymers and copolymers, having a weight average molecular weight Mw of at least 120 000 daltons; wherein said fiber producing device is rotated at a speed of at least 10 000 revolutions per minutes (RPM). The invention also relates to said polyolefin fibers, and to articles comprising said fibers.

摘要： The present invention relates to fibers, particularly to as-spun fibers, having improved properties, in particular improved bonding performance and mechanical properties. In particular, the present invention relates to fibers comprising a metallocene random copolymer of propylene and one or more comonomers, said metallocene random copolymer having a broader molecular weight distribution. The present invention further relates to nonwovens comprising such fibers and to a process for producing such fibers and nonwovens. The fibers and the nonwovens of the present invention are characterized by improved properties, in particular improved bonding performance and mechanical properties, when compared to the prior art fibers and nonwovens.
