A novel halogen adduct of ethylene sulfide, wherein X is Br, Cl or I, is prepared and used as an oxidation stabilizer in a stabilizer system for an ethylene sulfide polymer to prevent the oxidation degradation of the polymer, particularly during processing. In a preferred process the oxidation stabilizer in the system is formed in situ in the polymer by polymerizing ethylene sulfide in the presence of from about 0.04 to 4 percent of Br2, Cl2 or I2. A thermal stabilizer is added also to the polymer before high temperature processing to prevent thermal degradation.
