油墨行业既需要有石油树脂要较高的软化点和较浅的色相,又需要石油树脂要有较高的正庚烷值。本文探讨通过改进聚合工艺和原料,开发满足高级油墨需求的双环戊二烯石油树脂。
The ink industry needs both a higher softening point and a lighter hue of the petroleum resin, and a higher n-heptane value for the petroleum resin. This article explores the development of dicyclopentadiene petroleum resins that meet the advanced ink needs by improving polymerization processes and raw materials.
