Polymers experiment

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.
