| titleOfInvention | AQUEOUS BINDER COMPOSITION |
| abstract | The present invention relates to a process for the preparation of an aqueous binder composition, the process comprising at least the following steps A) and B): A) preparation of a carboxylic acid-functional vinyl polymer (polymer A) by polymerization in emulsion of a monomer A composition comprising the following monomers: Ai) at least one carboxylic acid-functional olefinically unsaturated monomer; and Aii) at least one olefinically unsaturated monomer different from Ai); B) preparing the vinyl polymer (polymer B) by emulsion polymerization of a monomer composition B in the presence of the polymer A wherein the monomer composition B comprises the following monomer (s): Bi) at least one olefinically unsaturated monomer; Bii) optionally an olefinically unsaturated monomer having a carboxylic acid functionality other than Bi); wherein at least a portion of the carboxylic acid groups of polymer A is deprotonated to obtain ionic or potentially ionic water dispersion groups; wherein the acid number of the polymer B is lower than the acid number of the polymer A; wherein the weight average molecular weight (Mw) of polymer B is greater than the weight average molecular weight (Mw) of polymer A; wherein the glass transition temperature of polymer B is less than or equal to that of polymer A; wherein the weight ratio of polymer A to polymer B is in the range of 5:95 to 95: 5; and whereby step A) comprises at least a first polymerization stage of a monomer composition (A1) carried out in the presence of a chain transfer agent (C1) having a solubility in water of at least 5 g / l and a second subsequent polymerization stage of a monomer composition (A2) carried out in the presence of a chain transfer agent (C2) having a solubility in water of at most 0.5 g / 1, and whereby the second polymerization stage of step A) is carried out in the optional additional presence of the chain transfer agent (C1) having a solubility in water of at least 5 g / l at wherein the concentration of the chain transfer agent (C1) having a solubility in water of at least 5 g / l in the second polymerization stage of step A) is at most 35 mol% , relative to the total molar concentration of chain transfer agent (C1) and chain transfer agent (C2) present in ns the second polymerization stage of step A). |
