Light scattering characterization of constituent copolymers from polyacrylate latices

Abstract

The method described is based on static light scattering measurement of solutions obtained by the direct dissolution of latex in a suitable organic solvent without intermediate isolation of solids. In the case of latices of acrylate copolymers with acrylic or methacrylic acid, often used in the paint industry, 2-ethoxyethanol proved to be the best solvent for this purpose. Static light scattering can also be used to estimate the mass and size of the dispersion particles prior to their dissolution.
