双环戊二烯主要来自裂解副产品碳五馏分,随着国内乙烯及石油催化裂解装置规模的不断增大,碳五馏分资源也越来越丰富。双环戊二烯的解聚、自聚合、加氢改性、氧化改性、复合改性聚合等拓展了双环戊二烯的应用,其独特的性能和多样化的应用功能,促进了树脂等多个行业的迅速发展。本文就双环戊二烯的制备及其改性应用加以详述。
Dicyclopentadiene mainly comes from the carbon-5 fraction of cracked by-products. As the size of domestic ethylene and petroleum catalytic cracking units continues to increase, the carbon-5 fraction resources are also becoming more and more abundant. Dicyclopentadiene depolymerization, self-polymerization, hydrogenation, oxidation modification, composite modified polymerization to expand the application of dicyclopentadiene, and its unique performance and diverse applications, and promote the resin and more A rapid development of the industry. This article describes the preparation and modification of dicyclopentadiene.
