Poly(acrylic acid) [9003-01-4] forms a complex with C8H17C6H4O(CH2CH2O)nH [9036-19-5] (average n = 9.2), and the complex is precipitated from aqueous solution by the addition of H(CH2)nNH2.HCl (I) (n = 1, 4, 6, 8, or 12) or H2N(CH2)nNH2.2HCl (II) (n = 3, 4, 6, or 8) to the solution At high concentrations of the amine salt, the precipitate is redispersed. The I are more effective than the II for precipitating the complex, and the precipitation and redispersion occur at lower salt concentrations with increasing alkyl chain length of the amines.
