Introduction

The series products are high-molecular compound polymerized with starting agent, epoxy propane and cyclohexane polyamines of different performance such as propylene glycol, octadecanol, resin of different types. Some products are the outcome of cross-bonding of epichlorohydrin and socyanate or auto-agglutination after reaction with different saturated materials. The products are in two major categories: water soluble and oil soluble, totally over 80 kinds. They are particularly used for de-emulsifying dehydration of crude oil of different kinds, water rinsing in oil refinery or used as accessory ingredient for electro-desalting.
