XU Huiming, SUN Chunshui, FU Jiansong, et al. Synthesis of ethylidene norbornene[J]. CIESC Journal, 2014, (1): 32-38.DOI: 10.3969/j.issn.0438-1157.2014.01.004.
Regarding to the ongoing demand for poly(ethylene propylene diene monomer) (EPDM)
ethylidene norbornene (ENB) as its co-monomer has attracted important attention. In this paper
synthesis mechanism and technology
production status and market trend of ENB are reviewed. The discussion about synthesis processes of ethylidene norbornene is divided into two parts
one is process optimization for side reaction control in the part of vinyl norbornene (VNB) synthesis by Diels-Alder reaction between butadiene and cyclopentadiene obtained from (di)cyclopentadiene by high temperature degradation
the other is influence of different types of catalysts in the VNB isomerization process.
