Dimethylsulfoxide for use in the manufacture of formulations for agricultural use

Abrégé

Provided is a process for obtaining a film or film-forming article. The process includes a) providing a solvent system comprising at least one molecule bearing a sulfoxide function, where the solvent system has a water content of less than 1000 ppm by weight and having a pH of greater than or equal to 6. The process also includes b) preparing a polymer solution, either by dissolving the polymers in the solvent system or by synthesizing the polymers in the solvent system. The process also includes c) removing the solvent system to obtain the film or the film-forming article.
