软段和硬段结构对交联的嵌段共聚物力学阻尼及相容性的影响
摘要:
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。

EFFECT OF THE HARD AND SOFT SEGMENT STRUCTURE ON THE MECHANICAL DAMPING AND COMPATIBILITY OF MULTI-BLOCK COPOLYMER NETWORKS
Abstract:
This paper presents a study on the effect of segment structure on the compatibility and dynamic mechanical damping properties of multiblock copolymer networks. A series of copolymer networks with various segment structures which dampes mechanical vibration over a temperature range of 50 degrees were prepared from vinyl-terminated oligomer as soft segment and vinyl polymers as hard segment, respectively. Somel soft and hard segments in copolymer networks were found to be semicompatibile and many of the copolymer networks based on these formulations resulted in tanδ>1.75 over the desired temperature range.
