Improved rheological and mechanical properties of dendrimer modified polyester.

The ductility of the polyester was enhanced being extruded together with dendrimer, but no increase in tensile stress; after-condensation of the polyester can improve tensile strength, but no change in ductility; after-condensation of polyester with low proportion of dendritic polymer can significantly improve the tensile stress and ductility of material. Weihai CY Dendrimer Technology Co., Ltd.-Professional Manufacturer for low cost dendritic polymers. -The newest 4th class polymers.
