Abstract
Second-order rate constants for the reaction of 5-dimethylamino-1-naphthalenesulfonyl chloride with butylamine in chloroform in the presence of glymes as oligomer cosolvents were measured by fluorometry. These cosolvents exhibit polymer effects characterized by acceleration the extent of which depended on the chainlength of the cosolvent molecules as well as the volume fraction of the cosolvent. Polymer effects by oligomer cosolvents on chemical reactions between two low molecular weight species are explained by the thermodynamics of the polymer solution.
