摘要:
process for the preparation of biodegradable polymeric systems applied to the controlled release of agrochemicals and products. The present invention relates to a process for preparing biodegradable polymeric systems applied in the controlled release of agrochemicals. More specifically, the present invention relates to a process for obtaining two types of systems. In the first system, the agrochemical is mixed with a biodegradable polymer through melt processing and then granulated and / or molded for application. In the second type of system, the agrochemical is incorporated into nanoparticles that are mixed with a biodegradable polymer through melt processing and / or granulation for application. The present invention also relates to possible formulations of these systems, which are prepared with different biodegradable polymers blended by melt processing with incorporated agrochemical-containing agrochemicals or nanoparticles. These agrochemicals are of various nature as long as they are resistant to melt processing and may or may not have compatibility with the polymer. The use of nanoparticles allows greater control over the rate of released agrochemicals due to the better interaction these particles have with the polymer matrix.processo para o preparo de sistemas poliméricos biodegradáveis aplicados à liberação controlada de agroquímicos e produtos. a presente invenção diz respeito a um processo para preparar sistemas poliméricos biodegradáveis aplicados na liberação controlada de agroquímicos. mais especificamente, a presente invenção refere-se a um processo de obtenção de dois tipos de sistemas. no primeiro sistema, o agroquímico é misturado com um polímero biodegradável através de processamento no estado fundido sendo após granulado e/ou moldado para aplicação. no segundo tipo de sistema, o agroquímico é incorporado em nanopartículas que são misturadas com um polímero biodegradável através de processamento no estado fundido passando por granulação e/ou mold
