| Abstract: | The titration curves of latex dispersions of ethyl acrylate — methacrylic acid copolymers have a rather complex shape which indicates a strong dependence of the apparent dissociation constant of carboxylic groups on the degree of neutralization and copolymer composition. These dependences seem to be related to changes in the macroscopic structure (swelling and disintegration) of dispersion particles during alkalization. |
