Method for preparing aliphatic polythioether

Abstract

Disclosed is a method for preparing aliphatic polythioether. In the method, aliphatic polythioether is obtained by polymerization reaction using a sulfur-carbon compound and an oxygen-containing monomer as raw materials and using Lewis base as a catalyst, and the polymerization reaction is performed under a self-generated pressure at 80˜180° C. Based on the defects of the traditional preparation process of aliphatic polythioether, the disclosure provides a bran-new synthetic routine in which a new process for preparing polythioether in one-pot reaction is achieved through oxygen-sulfur exchange reaction between the sulfur-carbon compound and the oxygen-containing monomer.
