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 DEG C to about 126 DEG C. The reactive blending can further take place in the presence of an organically modified nanoclay. 本发明涉及制备全同立构聚丙烯基复合材料的方法，其包括：将全同立构聚丙烯均聚物、用羧酸酐或呋喃型部分接枝的聚丙烯(如马来酸酐接枝的聚丙烯)和氨基硅烷(如(3-氨基丙基)三乙氧基硅烷)反应性共混以制备全同立构聚丙烯基复合材料，以便该全同立构聚丙烯基复合材料的结晶温度为约120℃至约126℃。该反应性共混可在有机改性纳米粘土的存在下进步发生。
