The modified C_5 petroleum resin is synthesized by cationic polymerization with C_5 fraction and small amount of propylene as raw material.A sizing agent can be easily made by emulsifying this modified resin.The results show that the optimal conditions of synthesis is as follows:130℃ as the thermal polymerization temperature,0.70 MPa as the thermal polymerization pressure,40℃ as the reaction temperature,3 hours of reaction time,1.8%(mass fraction) as the catalyst used,40% (volume fraction) as the dissolvent used.Under the optimal conditions,the hue of product can reach Gardnar level 8,the yield coefficient can surpass 52%,the softening point can be lower than 80℃,and the melt viscosity can be about 250 mPa·s.
