A polymer composition for producing gel extruded articles is described. The polymer composition contains polyethylene particles combined with a plasticizer. The polyethylene particles are particularly selected so that the particles rapidly form a homogeneous gel-like material when combined with the plasticizer during gel processing. In one embodiment, the polyethylene used to produce the particles has a relatively low bulk density. Alternatively or in addition, the particles can have a carefully controlled particle size distribution. Polymer articles such as fibers and films can be produced having little to no imperfections.

This invention relates to eco-friendly solutions and gels for making high strength ultra-high molecular weight polyolefin (UHMWPO) fibers, films, filters, membranes by solution and gel spinning techniques. This invention also makes soft, strong, oriented, and elastic fibers from styrenic block copolymers. The polymers are first dissolved or dispersed in a cyclic terpene. In some embodiments, the fibers are extruded or drawn from the solution or gel, and cooled to form a gel filament. In some embodiments, the fibers and films are soft and elastic by making the spinnable solution or gel from polyolefin and styrenic block copolymers or other elastomeric polymers in cyclic terpene. In some embodiments the fibers and films produced can be oriented by stretching or drawing in the gel state before and/or during and/or after removal of cyclic terpene.

An infrared reflecting fiber includes 76.0 parts by weight to 88.5 parts by weight of a carrier, 1.8 parts by weight to 4.0 parts by weight of an infrared reflecting composition, 2.5 parts by weight to 7.5 parts by weight of a titanium dioxide containing composition, and 6.0 parts by weight to 16.0 parts by weight of a color adjusting composition. The carrier includes polyethylene terephthalate (PET). When a content of 5.0 wt % to 7.5 wt % of the infrared reflecting composition and a balance of the carrier are mixed together to form a first fiber, a maximum infrared reflectivity of the first fiber is between 61% and 70%.

The present invention relates to preparation of heterogeneous mixtures of (carboxylated) vinyl ester/ethylene dispersions, such as vinyl acetate/ethylene (VAE) dispersions with polyamideamine-epichlorohydrin (PAE) wet strength resins having a reduced amount of halogenated organic compounds, such as less than 1500 ppm. The dispersion offers extremely low free and bound formaldehyde levels combined with wet tensile strength for use in non-woven textile and paper applications.
