C9 petroleum resin was prepared by thermal polymerization from C 9 distillate fractions of ethylene pyrolysis in this paper .Influence of the reaction condition (reaction time ,temperature and pressure) on the yield and chroma ,petroleum resin bromine value and diene value of solvent oil was investigated .The cracking crude C9 fractions were analyzed by infrared spectrum (IR) .The softening point and chroma of petroleum resin was also measured with standard test .The experimental results showed that the composition of C 9 distillate fractions was very complex , and the main active ingredients were styrene and its homologues .The petroleum resin yield increased with the increase of reaction time or temperature ,when the reaction temperature was above 240 ℃or the time was beyond 8 h ,the yield was tend to stabilize gradually .With the extension of reaction time ,the bromine value , diene value of solvent oil and the softening point of resin declined gradually while the chroma of resin increased . The optimal reaction conditions were determined as follows : the reactive time and temperature were 230 ℃ and 8h respectively ,the reaction pressure was 0 .6 M Pa .
