【Abstract】 Thermoplastic polyester ether elastomer (TPEE)with high melt strength and high melt viscosity was prepared by means of blocking special segment into the chain of TPEE and extending the molecular chain by polymer reaction extrusion.When the melt flow rate of the TPEE was less than 2g/10min and melt strength index was less than 3,the TPEE could be procesed easily by means of extrusion blowing molding,having excellent physical properties and being suitable for the application to many fields.更多还原
