    摘要: The invention includes a siloxy-imine functionalized rubbery polymer, which exhibits good reinforcing characteristics and filler dispersing effect, a method for making, and a rubber composition including the same. In one embodiment, a process for manufacturing the functionalized rubbery polymer includes polymerizing a conjugated diene monomer using an organolithium compound as an initiator in a hydrocarbon solvent. Next, an active terminal end of the polymer is reacted with a functionalized terminating agent, represented by the general formula: RCH═N(CH2)XSi(OR1)YR23-Y,   Formula (1) wherein R represents a group consisting of an aryl or substituted aryl having 6 to 18 carbon atoms, or a heterocycle or heteroaryl having 3 to 18 carbon atoms; R1 and R2 each independently represents a group having 1 to 18 carbon atoms selected from an alkyl, a cycloalkyl, an allyl, and or aryl; X is an integer from 1 to 20; and Y is an integer from 1 to 3.

    摘要: The present invention is based on the unexpected discovery that the fluid resistance of hoses can be greatly enhanced by adding a chlorinated paraffin to a chlorinated polyethylene elastomer or a chlorosulfonated polyethylene elastomer which is used as the tubular inner core layer of the hose. Hoses made using this approach offer the advantage of having improved resistance to modern automotive fluids, including power steering fluid, transmission fluid, and the like, without compromising flexural characteristics or burst strength. Accordingly, the hoses of this invention provide a longer service life and better reliability then hoses made utilizing conventional technology. The present invention more specifically discloses a hose which is comprised of (1) an elastomeric tubular inner core layer defining a lumen, (2) a friction layer, and (3) an elastomeric cover, wherein the elastomeric tubular inner core layer is comprised of (i) a chlorinated elastomer selected from the group consisting of epichlorohydrin, polychloroprene, chlorinated polyethylene and chlorosulfonated polyethylene, (ii) 1 phr to 50 phr of a chlorinated paraffin, and (iii) 30 phr to 120 phr of carbon black. It is typically preferred for the chlorinated elastomer to be chlorinated polyethylene or chlorosulfonated polyethylene.
