树枝状聚合物可以改进热塑性树脂的应变-硬化特性、熔体强度和熔体流变学<?xml:namespace prefix="o" ns="urn:schemas-microsoft-com:office:office"></?xml:namespace>
树枝型聚合物改性剂的存在对PET树脂中的结晶度几乎没有影响，在低剪切下表现出高熔体粘度的树脂在模塑机和压出机中进行制造时表现出更少的流下倾向，以及表现出良好的熔体强度。在高剪切水平下熔体粘度的降低可改善树脂的熔体加工性能，特别是用于异型挤出和螺杆注塑设备中。最新的第四代高分子材料-高性价比树枝状聚合物—晨源分子新材料
5. Dendritic polymer can improve strain-curing, melt strength and melt fluidity of thermoplastic resin.
Dendrimer almost has no effect on crystallization of PET, under low shear strength, it shows high viscosity, low fluidity and high melt strength, while under high shear strength, low viscosity could improve processing performance of resin, especially in extrusion and injection machines.
