This crosslinking agent is stable at room temperature and very readily initiates crosslinking. The crosslinking agent is prepared by reacting a compound having isocyanate group(s) with cyclodextrin at 65.degree. C. or below in water, and recovering the clathrate compound from the water.

Abstract: Maltooligosaccharide syrup is hydrogenated under nickel catalyst and high pressure so as to reduce the end-groups of the maltooligosaccharide syrup. The reduced syrup and cyclodextrin are mixed, and the volatile corrosion inhibitor is included by means of the cyclodextrin to form cyclodextrin clathrate compound of volatile corrosion inhibitor. The cyclodextrin clathrate compound of volatile corrosion inhibitor is mixed with a thermoplastic synthetic resin, such as polypropylene, polyethylene, ethylene-vinyl acetate copolymer, polyvinyl chloride. Then, the thermoplastic resin mixed with the volatile corrosion inhibitor is formed in a desired shape, by way of blown-film extrusion, injection molding or expansion molding.The thus obtained rust preventive comprises a thermoplastic synthetic resin including a cyclodextrin clathrate compound of volatile corrosion inhibitor.

Abstract: A method of manufacturing polychromatic artificial yarns incorporating liquid crystals is provided.According to this method, a transparent film sheet of plastic or other suitable material having a row of a plurality of longitudinally extending grooves on its outer surface is prepared and then coatings of micro-encapsulated liquid crystals, and particles of an ultra-violet light adsorbent are applied onto the grooves. After these processes, the entire outer surface of the film sheet is coated with a thin layer of carbon black and is then covered adhesively with another transparent film sheet of the same material. The entire material is finally cut out, across the second and first mentioned film sheets, longitudinally along the grooves to produce linear strips to be spun into yarns.
