Abstract

A polythioether prepolymer including functional groups capable of being obtained by the reaction: of at least one compound T having a number f of thiol functional group number selected from 2, 3, 4 and 6, with at least one compound E having a number g of epoxy functional groups number selected from 2 and 3. Also, a method of preparation for this prepolymer, a composition including this prepolymer and an oligomer as well as its use as a mastic and a polythioether polymer obtained from this polythioether prepolymer with an oligomer.
