Study of the Impact Resistance of Physically and Dynamically Vulcanized Mixtures of PP/EPDM

Abstract: Summary: Physically and dynamically vulcanized (TPV) mixtures of polypropylene (PP) and ethylene propylene diene terpolymer (EPDM) are prepared by extrusion in order to improve the impact resistance of PP. To enhance the chemical compatibility and provide better interaction between the PP and EPDM in the physical mixtures, both polymers are modified with maleic anhydride (MAH) in solution using xylene as solvent and dicumyl peroxide (DCP) as initiator. The qualitative and quantitative determination of the degr… Show more

“…Recently, researches have been devoted to this topic [9][10][11][12] . The alkyd resins are a good alternative for obtaining environmentally friendly hybrid coatings (waterborne resins); since they can be modified by addition reactions with other materials through double bonds, offering the access to other structures and materials with novel and enhanced properties [13][14][15] .…”

“…These materials are used, for example, in automobile [1], packaging [2], and resin [3] industries. These materials can be easily accumulated and remained in the environment for a long time, which is hazardous to the environment [2].…”

“…La funcionalización en fundido, a diferencia del proceso en solución, no requiere grandes cantidades de solventes y lo hace un proceso práctico para la producción a gran escala [9] . El AM es el monómero más usado, debido a que es un poderoso receptor de electrones [11][12][13][14][15] . La reacción de funcionalización se lleva a cabo por radicales libres usando un peróxido como iniciador, por su baja volatilidad y buena solubilidad, y compatibilidad con las poliolefinas [1,4,16] .…”

“…El PEBD es altamente hidrofóbico, por lo tanto para ser mezclado con otros poliméros que tengan grupos polares, lo ideal es realizar la modificación química del PEBD con monómeros polares, para obtener así una mezcla compatible [1][2][3][4][5][6][7] . La necesidad de mejorar las compatibilidad de poliolefinas con otros polímeros polares, se ha convertido en tema de interés especialmente en áreas como recubrimientos, mezclas y composites [8][9][10][11][12][13][14] . En las últimas décadas se han generado investigaciones para funcionalizar poliolefinas usando anhídrido maleico [11,12] .…”
