Polysulfide polymer was found in the 19th century. At present, this polymer consists of the repetition of disulfide linkage and diethyl formal and has SH terminals. This liquid polymer (LP) is cured by lead dioxide. We studied polysulfide polymerization and elastomeric mechanical properties of cured
The results of our studies show that liquid linear polysulfide polymers of an average molecular weight 4260-1030 g mol 01 can be obtained by the reaction of sodium tetrasulfide and 1,1 -[methylenebis(oxy)]-bis-[2-chloroethane] in the presence of 2.0-5.0 mol of hydrazine and at least 4.0 mol of sodiu
