STUDY ON THE EFFECT OF POUR POINT DEPRESSING OF STYRENE-OCTADECYL ACRYLATE

Wei Ding, Zhang Rong-ming

Abstract

The co-polymerizations of styrene and octadecyl acrylate by BPO as initiator in tolune are studied. The IR-Spectra of the copolymer is analyzed. The effect of pour point depressing of the copolymers to Daqing crude oil is also dealt with. By adding a mass fraction of 0. 005-0. 01 of PSOA-4 to Daqing crude oil (pour point 35°C) and then having it thermally treated at 70° C, we can reduce its pour point from the original 35°C to 16-17°C.
