WebDr. Keli Christopher leads students through a series of fun, hands on experiments designed to learn more about the properties of polymers. WebIn this experiment, the chemistry of silicones will be investigated by preparing “bouncing putty”, a silicone polymer, via the hydrolysis of dichlorodimethylsilane. The silicone, containing residual hydroxyl groups will be cross-linked using boric acid. This trifunctional acid, B(OH)3, which also

WebSep 12, 2024 · In this case, the relationship is described by the Mark-Houwink equation: (4.2.1) [ η] = K M α. In this equation, [η] is the intrinsic viscosity; that's the viscosity attributed to the solute, rather than the viscosity of the solvent itself. M is the molecular weight. K and α are constants for a particular polymer. WebMonomers may have been able to spontaneously form polymers under the conditions found on early Earth. For instance, in the 1950s, biochemist Sidney Fox and his colleagues found that if amino acids were heated in the absence of water, they could link together to form proteins 10 ^{10} 1 0 start superscript, 10, end superscript.Fox suggested that, on early … WebJun 21, 2012 · By Amy Cowen on June 21, 2012 6:51 AM.
