Review on polyolefin elastomers with dynamic-chemical cross-linking
摘要
Abstract
Polyolefin elastomer(POE)is a high-end polyolefin material that is copolymerized from ethylene and α-olefin.It has excellent properties such as chemical stability,weather resistance and electrical insulation,and is widely used in various fields such as photovoltaic,automobile and cable.Dynamic-chemical cross-linking(DCC)can further improve its mechanical properties and thermal stability,and expand its application range while ensuring its processability.This paper reviews the preparation methods of DCC POEs,including one-step direct cross-linking and multistep cross-linking after functionalization.The functionalization methods,such as post-functionalization and copolymerization of ethylene and functional monomer,are elaborated.The characterization methods of DCC POEs and the relationship between their chain structure,aggregation structure and properties are discussed.The future prospects of DCC POEs are also presented.This paper aims to provide theoretical guidance and technical support for the controlled synthesis,structure-activity relationship study and high value application of DCC POEs,and to promote the innovation and development of high-end polyolefin materials.关键词
