    摘要: Rubber particles, to be used as fillers or extenders for various composite polymer systems, are chlorinated by a gas-solid phase reaction with a chlorine-containing gas. A composite polymer containing the chlorinated rubber fillers or extenders exhibits a higher flexural modulus than if prepared using an unchlorinated rubber filler or extender. Chlorination of the rubber particles is carried out by contacting the finely divided rubber particles with a chlorine-containing gas comprising at least about 5 volume percent chlorine. Advantageously, the chlorine can be diluted with air, nitrogen or other essentially inert gases and may contain minor amounts of fluorine. Improved performance is obtained with nitrogen dilution of the chlorine gas over air dilution. Improved polymer composite systems having higher flexural modulus result from the use of the chlorinated rubber particles as fillers instead of unchlorinated rubber particles.

    摘要: A duct cleaning device, including a flexible conduit with a first, inlet end and a second, outlet end. An end cap with a central hole is attached to the first end; a connector adapted for coupling the device to a vacuum hose (or the inlet of a vacuum cleaner) is attached to the second end. A flexible, radially-projecting brush is attached to the exterior of the conduit, extending helically about the conduit; a plurality of throughholes (some of which carry flexible, radially-projecting tubes) are positioned near the brush. In operation, the device is connected to a source of vacuum. The first end is rotated while being moved into (or removed from) a duct, while the brush sweeps the interior surface of the duct to dislodge particulates of house dust and other contaminants from the surface. The particulates are swept into the conduit through the hole in the end cap and the throughholes in the conduit. The conduit and the brush are flexible, so the device can readily traverse offsets and bends in duct systems without damaging flexible plastic or fiberglass ducts.
