摘要： A solvent-free process for making a polyol fatty acid polyester composition useful for preparation of polyurethanes is described. These compositions are preferably made by reaction of a natural oil (from plant or animal) with a multi-functional hydroxyl compound derived from a natural source, such as sorbitol, in presence of an alkali metal salt or base such as potassium hydroxide as a catalyst which also acts to saponify the reaction mixture. The hydroxyl content of the prepared composition depends on the amount of the multi-functional hydroxyl compound used in the preparation. In another embodiment, the hydroxyl groups of these compositions are reacted with an isocyanate, such as the polymeric diphenylmethane diisocyanate (also known as 4,4′-diphenyl methane diisocyanate, or MDI) to form polyurethanes in a conventional manner.

摘要： A method using irradiation with optical light in the presence of a chemical dissolved in a solvent which chemical reacts with the surface in the presence of the irradiation to modify the surface (12A, 104A, 202A, 304A, 402A, 502A) of a substrate (12, 104, 202, 304, 402, 502) is described. The light can be pulsed or continuous. The method is significantly enhanced by the presence of water (14, 124, 204, 308, 410, 508) as the solvent containing the dissolved chemical on the surface. The treated surfaces are more paintable and bondable.

摘要： A system and method for uniformly coating one or more fibers (10) with particles of a material is described. The method uses a vibrator preferably an acoustic speaker (17b) in a housing (17c) to fluidize the particles (P.sub.1) in a chamber (17 or 30) to deposit them on spread fibers (10b). The fibers can be in the form of a tow of fibers. After the particles are coated on the fibers, the particles can be bonded to the fiber such as by using a heater (19). The resulting product has a uniform deposit of the particles and in the case of the tow of fibers can serve as a prepreg for laminate structures to be produced from the coated tow of fibers.

摘要： Epoxy resin polyglycoside-based cured polymers and process for the preparation are described. A particular epoxy resin precursor is the diglycidyl ether of bisphenol A. A particular glucose based polymer is a glucose malic acid ester-vinyl copolymer. The polymers have a degree of biodegradability because of the polyglycoside as well as elevated temperature stability and are useful in transportation vehicle settings. Natural source fillers, such as cellulose fibers, which are treated or untreated, exfoliated clays or exfoliated graphite can be used.
