Abstract
Pyrolysis of petroleum hydrocarbons (including diesel pyrolysis) aimed at obtaining polyethylene also creates certain liquid products which can be used for making so-called petroleum resins (PRs). The C9 fraction from pyrolysis contains among others, styrene and its derivatives, indene and pentanodiene. Petroleum resins with epoxy groups (PREs) have been synthesized by oligomerization of unsaturated components of the C9 fraction in the presence of 4,4'-azo-bis-[2,3-epoxypropoxy-4-cyano-pentanenitrile] (AEPCP) used as an azoinitiator. The influence of azoinitiator quantity, temperature and time of oligomerization upon the yield and characteristics of the resulting functional petroleum resins has been evaluated. The structure of the products was confirmed by IR-spectroscopy. Our PREs have potential applications as active additives to industrial epoxy resins based on Bisphenol A.
