Hyperbranched polyester can significantly improve the many performance of PET processing.
(1) hyperbranched polymer has greater impact on rheological performance of PET, when HBPE-OH addition level is 0.5%, the torsion decreases by 60%, in 10% of the added amount can decrease by 77%; (2) HBPE/PET mixing system has good thermal stability to meet the general using conditions and under the high temperature processing, PET will not degrade though with hydroxyl terminal groups; (3) Through SEM, it proves that HBPE-OH can bring brittle-ductile transition to PET material. From "Research on PET blending modification by hyperbranched polyester " Ji Lianqin, Beijing Institute of Technology 2010 Master Thesis. Weihai CY Dendrimer Technology Co. Ltd.-Professional Manufacturer for low cost dendritic polymers.
