A polythioether has the formulaR.sup.1 --�--R.sup.2 --S--CH(CH.sub.3)--S--!.sub.n --R.sup.2 --R.sup.1whereinR.sup.1 denotes a thiol group, a hydroxyl group, an unsubstituted amine group, a monoalkyl-substituted amine group, a monovalent radical substituted with at least one hydroxyl group, unsubstituted amine group or monoalkyl-substituted amine group, or a group that is non-reactive in the presence of an acid catalyst,R.sup.2 denotes a divalent radical, andn is an integer from 1 to 60.The polythioether is a liquid at room temperature and pressure.
