Abstract
Using a combination of static light scattering, potentiometry, and vis cometry, structural changes of latex particles of ethyl acrylate-metha crylic acid (20-70 wt%) copolymers during neutralization in the presen ce of methanol were investigated. It was found that the latex particle s disintegrate into small subparticles, swell, and at a high content o f methacrylic acid units dissolve. Disintegration of latex particles i s explained by considering the particles as agglomerates formed during polymerization by coalescence of smaller particles.
