Definitions
- the present invention relates to a process for the preparation of aqueous dispersions of copolymers by emulsion polymerization of ethylenically unsaturated monomers in the presence of at least one initiator or initiator of free radicals.
- Aqueous dispersions based on butadiene, in particular styrene / butadiene and acrylonitrile / butadiene latexes are widely used in various applications, such as paper processing agent and the manufacture of rubber, for example tires. It is well known that the emulsion polymerization of butadiene or its copolymerization with other monomers leads to a crosslinked polymer whose degree of branching increases with the conversion rate. This crosslinking has a detrimental effect on the use properties of the latexes obtained. For example, it can affect the coalescence of latex particles during coating applications, such as coating paper, or contribute to poor control of the hardness of rubber, thereby limiting its processability.
- the commonly used transfer agents are mercaptans which, although having a very low residual content in the final latexes, induce an undesirable characteristic odor.
- the object of the present invention is to remedy the drawbacks of the prior art by proposing an effective polymerization process, resulting in good conversion of the monomers, which leads to latexes of copolymers having a low degree of crosslinking.
- This weak crosslinking can be used to reduce the mercaptan level and thus decrease the odor or increase the conversion rate without obtaining prohibitive crosslinking rates.
- the process for obtaining aqueous dispersions of copolymers consisting in polymerizing a mixture of monomers containing at least 60% by weight of butadiene and at least one monomer chosen from styrene, acrylic esters, vinyl nitriles optionally with up to 40% by weight of one or more other copolymerizable unsaturated monomers, in aqueous emulsion in the presence of one or more initiator (s) or initiator (s) free radicals is characterized in that at least one of the initiators or initiators or that the initiator or initiator is an ester of azocarboxylic acid of formula (I):

- the azocarboxylic acid esters of formula (I) can be prepared by a conventional two-step process comprising a first step of conversion of the azonitrile, by reaction with an alcohol, in the presence of HCl, according to the Pinner reaction, leading with the corresponding azoiminoether hydrochloride and a second hydrolysis step in the presence of the hydrochloride thus obtained. They can also be prepared by improved methods as described in documents DE 2 254 572, EP 80 275 and EP 230 586.
- esters can be prepared by reacting an azonitrile with an alcohol and hydrochloric acid in an aromatic solvent, with an HCl / azonitrile molar ratio> 2 when the alcohol is methanol and> 3 when the alcohol is ethanol or higher alcohol.
