    摘要: The invention is a cleaning device comprising of a shaft. The shaft has a hollow section and a lower end with a rim. The rim defines an opening at the bottom end of the shaft. The opening is located about the longitudinal axis and is in communication with the hollow section. The shaft also has one or more apertures that extend through the side of the shaft and are in communication with said hollow section. The shaft also has one or more slits that maybe in communication with the one or more apertures. The slit(s) run parallel to the longitudinal axis and may terminate before reaching the rim. The cleaning device is designed in such a way to easily allow a user to employ any flexible fabric or other suitable material in the cleaning device.

    摘要: Polyethylene terephthalate scrap material containing on its surface a chlorine-containing polymer such as, for example, polyvinylidene chloride or polyvinyl chloride, can be recovered and reused by melt-blending it with a polymer from a defined class of ethylene copolymers containing an epoxy group, and melt processing the blend in the same manner as virgin polyethylene terephthalate. The recovered and reprocessed polymer material has good physical properties and barrier properties.

    摘要: It has now been found that a unique combination of additives makes mineral-reinforced semi-crystalline polyamides readily processible by extrusion blowmolding to make hollow, stiff parts of various shapes. The compositions consist essentially of semicrystalline polyamide, 15-50 weight percent mineral filler reinforcing agent; 1-25 weight percent of an ionic copolymer of at least one alpha-olefin and at least one alpha, beta-unsaturated carboxylic acid in which the acid moiety is partially neutralized with metal ions, and 0.1 to 3 weight percent of fibrillar fluoropolymer resin. Percents are by weight of compositions.

    摘要: Inorganic fiber-reinforced thermoplastic articles are produced from precisely proportioned feed mixtures of particles of thermoplastic polymer, a polymer modifier and inorganic fiber bundles supplied, under specified conditions, directly to an injection molding apparatus. The articles exhibit exceptionally superior heat deflection temperature compared to articles produced from feeds which are precompounded prior to injection molding.
