Aqueous emulsion |
摘要 |
The invention relates to an aqueous emulsion comprising at least a vinyl polymer, said vinyl polymer comprising: a) 45 to 99 wt % of itaconate ester monomers having formula (I), wherein R and R′ are independently an alkyl or an aryl group; b) 0.1 to 15 wt % of ionic or potentially ionic unsaturated monomers; c) 0 to 54 wt % of unsaturated monomers, different from a) and b); and 0.9 to 54.9 wt % by weight of total monomers of a chaser monomer composition added subsequently and polymerized after the polymerization of monomers a), b) and c); wherein a)+b)+c) and the chaser monomer composition add up to 100%; and wherein the aqueous emulsion contains less than 0.5 wt % free itaconate ester monomers of formula I based on the total weight of the aqueous emulsion.; |

1. A coating composition comprising an aqueous emulsion comprising at least a vinyl polymer, said vinyl polymer comprising:
a) 45 to 99 wt % of itaconate ester monomers having formula I: wherein R and R′ are independently an alkyl or an aryl group; b) 0.1 to 15 wt % of ionic or potentially ionic unsaturated monomers; c) 0 to 54 wt % of unsaturated monomers, different from a) and b); and 0.9 to 54.9 wt % by weight of total monomers of a chaser monomer composition added subsequently and polymerised after the polymerisation of monomers a), b) and c); wherein a)+b)+c) and the chaser monomer composition add up to 100%; and wherein the aqueous emulsion contains less than 0.5 wt % free itaconate ester based on the total weight of the aqueous emulsion. |
