Abstract: A method of preparing a bio-polyol using coffee by-products, a polyurethane resin composition containing the bio-polyol, and a method of preparing a polyurethane foam using the same are described. The method simplifies the complicated process of extracting polyols from coffee and thus extracts bio-polyols within a short time, thus being advantageous in terms of cost and time.

Abstract: The present invention relates to poly(ether ketone ketone) (PEKK) polymers, a method for the manufacture thereof, to articles and composites made therefrom, to methods of making the composites, and composite articles including the PEKK composites. It was surprisingly discovered that by synthesizing the PEKK polymers from low-metal monomers and selectively controlling the relative amounts of reactants during the synthesis, PEKK polymers having unexpectedly improved melt stability can be obtained. The PEKK composites including the PEKK polymers are especially well-suited for fabrication of thick composite parts where melt stability of the polymer matrix is important.

Abstract: Provided is a method that can stably produce polyaryletherketone that has a high degree of polymerization and can be easily recovered. The method for producing polyaryletherketone includes: a polycondensation step of carrying out desalting polycondensation in a reaction solvent; and a cooling step of cooling a reaction mixture after desalting polycondensation is completed. When the method is implemented, the polycondensation step is carried out in a hydrophilic solvent under pressurized conditions, and the polymerization temperature in the polycondensation step is at or above the boiling point of the hydrophilic solvent at ambient pressure. In addition, the polymer content in terms of monomers at the time of cooling in the cooling step is from 1 part by mass to 50 parts by mass, per 100 parts by mass of the hydrophilic solvent in the reaction mixture.

Abstract: Surface-treated polymeric particles which are dispersible in water or an aqueous solution without the aid of any surfactant. Surface treatment of hydrophobic polymeric particles is carried out to increase the surface energy and to render the surfaces of the particles hydrophilic, thereby eliminating the need for a surfactant to disperse the polymeric particles in water or an aqueous solution. As such, a surfactantless slurry can be formed from the surface-treated particles for the fabrication of fiber-reinforced thermoplastic composite structures.
