Different polyesteramides hyperbranched polymers (HPEA1-6)/montomorillonite clay (MMT) nanocomposites were prepared with three different loading contents of clay (4, 10, and 15 wt%). The obtained nanocomposites were characterized via XRD, thermal analyses, and TEM. Generally, intercalation behavior was observed. The hyperbranched polyesteramides (HPEA1-6) were originally prepared by the bulky reaction between maleic anhydride (MAn), succinic anhydride (ScAn), and phthalic anhydride (PhAn) with either diethanolamine (DEA) or diisopropanolamine (DiPA). The resulting hyperbranched polyesteramides (HPEA1-6) were characterized by GPC, IR,1H-NMR, TGA, and DSC.

After the paper uses a unique domestic natural rubber Eucommia to establish a chemical link between the asphalt and the solubility of the powder, analyzed the structure of the double bond vulcanization gutta percha and the solubility of the powder, gutta percha and asphalt amino group of the reaction maleic anhydride, and so gutta appreciate and a chemical link. Analysis then grafted with maleic anhydride mix and low temperature, water stability and mechanical properties, aging resistance. The results found, gutta vulcanized rubber powder can be promoted, but enhance mixing; material properties are not obvious. Maleic anhydride grafted gutta percha is established after the reaction network vulcanized rubber powder and asphalt, so that performance significantly. : Less than 2% when the dosage was added gutta percha grafted SBS modified asphalt to improve its high temperature and aging resistance, without reducing the low-temperature performance, and 1.5% ash graft gutta SBS modified to be most significant .
