Abstract: Hybrid clays for obtaining nanocomposites useful in the automotive, aviation, construction and packaging industry, among others. The hybrid clay comprises clays intercalated with the itaconic acid (ITA) monomer or its derivative monooctadecyl itaconate (MODIT), and a process for the preparation of these hybrid clays and the process to obtain polyolefin/clay nanocomposites.

Abstract: The present invention relates to compatibilizers to be used for obtaining materials called polyolefin nanocomposites, microcomposites and polymer blends, and it includes the process for obtaining such compatibilizers. Such compatibilizers are obtained from the monomers of the organic compounds itaconic acid (ITA) or its monooctadecyl itaconate (MODIT) derivative. The compatibilizers are polyolefins grafted with those monomers, which are characterized by having functional groups with a hydrophilic character and a polymer backbone with a hydrophobic character. The compatibilizers of this invention are characterized by having controlled degrees of grafting of these monomers, and they can be used optimally in various applications.

Abstract: This invention reveals polypropylene composites to be used in the automotive, electronics, packaging and textile industries, which comprises a polypropylene homopolymer in a proportion ranging from 10 to 60% by weight, a natural reinforcement based on eggshells, and an antioxidant. This invention also reveals a natural reinforcement produced from eggshells obtained as an agroindustrial waste, the process to obtain said composite, and the process to obtain such reinforcement. By means of this invention, polypropylene composites using the natural reinforcement are obtained that have improved mechanical and thermal behavior when compared to polypropylene composites using traditional mineral reinforcements.
