Odd-shaped "Sponge-like" Particles Prepared by Non-aqueous Dispersion Polymerization

Korea Polymer Journal, Vol.2, No.1, 40-46, April, 1994

A method is described for the preparation of the core-shell latex particle containing a cross-linked core and a polar shell in submicron size range and of the odd shaped "sponge-like" aggregates in 3 to 5㎛ using non-aqueous dispersion (NAD) polymerization. These latexes were prepared by seeded semi-continuous dispersion polymerization in n-heptane, and sterically stabilized by the poly(12-hydroxy stearic acid)(PHS) type amphipatic stabilizer. The final shapes of the resulting core-shell dispersion particles were found to be greatly influenced by the detailed composition of the monomer mixtures in the reaction. The aggregates formed in this study were easily redispersed after settling under the influence of the gravity. The freeze-dried core-shell particles were easily redispersed in water containing an amine base.
