C_9石油树脂的改性

Modification of C 9 Petroleum Resin

本文涉及的改性石油树脂是用Ｃ９石油树脂与马来酸酐的加成物再与异辛醇反应后得到的。由于在改性石油树脂中引入了柔性和极性基团，使其与聚氯乙烯（ＰＶＣ）具有良好的共混性，提高了ＰＶＣ的抗冲性能。本文研究了Ｃ９石油树脂改性反应的最佳条件，以及改性石油树脂的用量对共混物机械强度的影响。

Modified petroleum resin(MPR)was prepared by reaction of isooctanol with the addition compound of C 9 petroleum resin with maleic anhydride.The introduction of polar and flexible groups into petroleum resin causes the latter to be easily blended with polyviny chloride(PVC)so as to enhance the impact strength of PVC.Optimum conditions for petroleum resin modification reaction and the influence of MPR quantity on the strength of the blend were also investigated.
