Abstract: This invention relates to a process for producing an isotactic polypropylene based composite, comprising: reactive blending of isotactic polypropylene homo-polymer; polypropylene grafted with a carboxylic anhydride or a furan type moiety such as maleic anhydride grafted polypropylene; and an amino silane such as (3-aminopropyl)triethoxysilane to produce an isotactic polypropylene based composite such that the crystallization temperature of the isotactic polypropylene based composite is in a range of about 120° C. to about 126° C. The reactive blending can further take place in the presence of an organically modified nanoclay.
