Publication number: 20090203826Abstract: 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.Type: ApplicationFiled: February 13, 2008Publication date: August 13, 2009Inventors: Michael Joseph Rachita, Kenneth Allen Bates, Vanessa Marika Riedlinger, Tang Hong Wong

Publication number: 20090197990Abstract: A lightweight finish composition, method of production and a method of application are provided. The lightweight finish composition comprises a resin dispersion, alkali metal phosphate, alkylolammonium salt of a polyfunctional polymer, and lightweight aggregate such as silica spheres. The lightweight aggregate has a density and weight that is less than those of sand. The combination of alkali metal phosphate and alkylolammonium salt of a polyfunctional polymer stabilizes the lightweight finish composition by preventing the lightweight aggregate from absorbing water, after production of the lightweight finish composition.Type: ApplicationFiled: April 13, 2009Publication date: August 6, 2009Applicant: Construction Research & Technology GmbHInventors: Markus Bohler, Michael Flynn
