Résumé : |
Stabilization of aqueous dispersions of copper phthalocyanine (CuPc) by water-soluble polymers was studied. The following polymers have been used: poly(N-vinyl caprolactame) (PVCL) of various molecular masses, poly(N-vinyl formamide) (PVFA), poly(i-propyl acrylamide) (PiPAA), copolymers of vinyl caprolactame with vinyl alcohol (CVCL-VA), ethyl hydroxyethyl cellulose (EHEC), poly(vinyl alcohol) (PVA) of various contents of acetyl groups and molecular masses. The wetting effect was observed only in the case of poly(vinyl alcohol) samples with residual contents of acetyl groups between 10 and 20%. These samples possess high surface activity and as a result show the stabilizing effect on CuPc dispersions. The data on the optical density of the CuPc aqueous dispersions with separated solid phase show that the most effective stabilizer of CuPc dispersions is PVA with 17% of CH,COO groups and molecular weight of 10,000-11,000. |
