LATEX FOR SOLVENT-FREE PAINTS HAVING IMPROVED WASHABILITY |
摘要 |
An aqueous polymeric emulsion prepared from a monomeric composition which comprises, for 100 parts by weight of the composition, 60-100 parts by weight of at least one acrylic or methacrylic ester derived from an acrylic or methacrylic acid and an alcohol having 1-12 carbon atoms; 0-40 parts by weight of at least one vinyl aromatic monomer; 0-5 parts by weight of at least one short-chain, alpha - beta -unsaturated mono- or polycarboxylic acid; and 0-3 parts by weight of at least one short-chain alpha , beta -unsaturated amide. Around 80-98 wt % of the monomeric composition is added to a reaction medium which already contains a partially polymerised pre-emulsion of 2-20 wt % of the monomeric components, the average particle size of the polymer in said partially polymerised pre-emulsion being no higher than 95 nm. Said aqueous polymeric emulsion is useful for preparing plasticiser-free and coalescing agent-free paints having excellent washability. |
