Modificación de Betún-Venezuela por reacción de Friedel y Crafts
In this work, a Venezuelan-bitumen of newtonian nature was modified by Friedel and Crafts reaction, changing it in new materials that present pseudoplastic characteristics, with very different properties from the original product. These new materials are harder and have less thermical susceptibility and allow us to use them in many applications such as paving and roofing. The modifications have been made with rubbers, PVC, phtalic anhydride, maleic anhydride, 1, 2-propyleneglycol, hexamethylenediisocyanate and toluylene-2,4-diisocyanate.
