Reversible derivatization of poly (aryl ether ketones)
A method of forming a polymer matrix composite using a soluble derivative of a poly (aryl ether ketone) (PAEK). The method includes mixing a starting PAEK polymer with a solvent and an acid, said solvent being selected from a group consisting of diethylether, tetrahydrofuran (THF), dioxin, and chlorinated solvents; reacting the PAEK mixture with a Lewis acid and a thiol compound in amounts effective to form a poly (aryl ether thioacetal) compound which comprises at least one thioacetal group; and impregnating a plurality of fibers in a solution comprising said poly (aryl ether thioacetal) compound.

A frequently-touched surface for use by multiple users includes a surface protected by a laminate structure. The laminate structure includes a self-sterilizing sulfonated polymeric outer layer, sulfonated to a certain % to kill at least 95% microbes within 30 minutes of contact. The self-sterilizing sulfonated polymer layer can be applied to the frequently touched surface by any of coating, lamination, and spraying. The sulfonated polymer in embodiment is selected from perfluorosulfonic acid polymers, polystyrene sulfonates, sulfonated block copolymers, sulfonated polyolefins, sulfonated polyimides, sulfonated polyamides, sulfonated polyesters, sulfonated polysulfones, sulfonated polyketones, sulfonated poly(arylene ether), and mixtures thereof. The sulfonated polymer has a degree of sulfonation of at least 10%.
SYSTEM AND METHOD FOR USING A VOC FREE LOW RADIANT FLUX LED UV CURABLE COMPOSITION
The present invention generally relates to a system and method for using a volatile organic compound (VOC) free low radiant flux LED UV curable composition, and more particularly to unique and novel uses of the composition such as one or two or more of a fire retardant, clear coat, composite material, resin, top coat, improved holdout coating, a sealant coat, and combinations of the same.
FINE FIBER PULP FROM SPINNING AND WET LAID FILTER MEDIA
A material comprising a fine fiber pulp is provided. The fine fiber pulp has a plurality of fine fibers have an average diameter of less than 1 micron and an average length of less than 1 millimeter. In embodiments, the fine fibers formed of a polymer. The material can be created according to a method in which the fine fiber strands are formed from a polymer melt or a polymer solution, the fine fiber strands are cooled to a temperature of less than −25° C. to increase brittleness of the fine fibers, and the fine fiber strands are granulated into the fine fiber pulp.
MULTI-COMPONENT SYSTEMS FOR PREPARING FOAMED PRODUCTS
Foamed products are produced using multi-component systems which are advantageously free of isocyanate. The components of the systems are combined, with the resulting mixture then undergoing curing and foaming to provide a foamed product, wherein the characteristics of the foamed product may be varied by selecting particular reactants to be present in the multi-component system. The systems employ at least one (meth)acrylate compound having two or more (meth)acrylate functional groups per molecule, at least one thiol compound having two or more thiol functional groups per molecule, at least one free radical initiator, at least one blowing agent, at least one surfactant, and optionally at least one promoter for the free radical initiator.
Pipe
A polyetheretherketone pipe of length greater than 250 meters and a residual stress of less than 5 MPa may be made using a calibrator device 2 which includes a cone shaped opening 6 arranged to receive a molten extruded pipe shaped polymer. Attached to the front member 4 is a vacuum plate 14a and successive vacuum plates 14b-14h are attached to one another to define an array of vacuum plates, the vacuum plates being arranged to allow a vacuum to be applied to a pipe precursor passing through opening 16. The vacuum plates 14 also include temperature control means for heating or cooling the plates and therefore heating or cooling a pipe precursor passing through the openings. With a vacuum applied to opening 6, 16 and heating/cooling the plates, an extruded hot plastics pipe is inserted into calibrator 2 via opening 6 and conveyed through opening 16 in plates 14, whereupon it is urged by the vacuum against the cylindrical surface defined by plates 14 to maintain its shape and the temperature of each plate is controlled to control the rate of cooling of the pipe precursor passing through. The pipe may be cooled at a relatively slow rate so that a pipe made from a relatively fast crystallising polymer crystalises and the crystallinity of the pipe along its extent and throughout its thickness is substantially constant.
