本文研究了链段结构对多嵌段共聚物网的相容性及动态力学阻尼性能的影响。分别以端乙烯基低聚物作为软链段,乙烯类聚合物作为硬链段,制备了一系列具有不同链段结构共聚物网。它们在大于50℃的温度范围,能阻尼机械振动。共聚物网中某些软链段和硬链段成分是半相容的。基于这些配方的许多共聚物网,在需要的温度范围,tanδ>1.75。 In this paper, the effect of segment structure on the compatibility and dynamic mechanical damping properties of multi-block copolymers was studied. A series of copolymer networks with different segments were prepared by using terminal vinyl oligomer as soft segment and ethylene polymer as hard segment, respectively. They can damp mechanical vibrations at temperatures over 50 ° C. Some of the soft and hard segments in the copolymer network are semi-compatible. Many copolymer networks based on these formulations have tan δ> 1.75 at the required temperature range.
