nanoparticles of acrylic terpolymers, their obtaining process and their applications. The present invention is directed to the production of nanoparticulate and multifunctional polymeric materials of spherical morphology comprising terpolymers obtained from vinyl monomers such as methyl methacrylate, vinyl pivalate and short carboxylic acids such as acrylic and methacrylic acids. in addition to long chain carboxylic acids derived from vegetable oil. Another embodiment of the present invention relates to the process of synthesis of spherical terpolymer nanoparticles, characterized by the emulsion polymerization reaction of vinyl monomers, preferably methyl methacrylate, vinyl pivalate (as a structural driver) and methacrylic acid. Another innovative aspect of the present invention concerns the use of fatty acids derived from vegetable oils, preferably acrylated and methacrylated long chain carboxylic acids, derived from oleic, linoleic and linolenic acids in the composition of the terpolymer. This invention has as its differential the fact that it contains spherical morphology nanoparticles that form nanostructured films showing opalescence without the addition of organic or inorganic fillers, which makes the material interesting for application as surface protection films, especially the surface of tooth enamel. .nanopartículas de terpolímeros acrílicos, seu processo de obtenção e suas aplicações. a presente invenção discorre sobre a produção de materiais poliméricos nanoparticulados e multifuncionais, de morfologia esférica, compreendendo terpolímeros obtidos a partir de monômeros vinílicos, tais como metacrilato de metila, pivalato de vinila e ácidos carboxílicos de cadeia curta, como os ácidos acrílico e metacrílico, além de ácidos carboxílicos de cadeia longa derivados de óleo vegetal. outra modalidade da presente invenção diz respeito ao processo de síntese de nanopartículas esféricas de terpolímeros, caracterizados pela reação de polimerização em emulsão de mo
