Abstract: A thermoplastic copolymer with a high sulphur content, having sulphur in an amount greater than or equal to 40% by weight, in relation to the total weight of the thermoplastic copolymer with a high sulphur content and at least one monomer having general formula (I): wherein: R1 and R2, equal or different from each other, represent a hydrogen atom; or R1 and R2, may optionally be bound together so as to form, together with the other atoms to which they are bound, a cycloalkene containing from 4 to 6 carbon atoms, saturated, unsaturated, or aromatic, optionally substituted with C1-C20 alkyl groups; the monomer having general formula (I) being present in an amount less than or equal to 60% by weight; the thermoplastic copolymer with high sulphur content having a complex dynamic viscosity (?*), at 160° C., comprised between 1×104 Pa.s and 8×106 Pa.s.

Abstract: Thermoplastic copolymer with a high sulphur content comprising sulphur in a quantity higher than or equal to 40% by weight, preferably ranging from 45% by weight to 90% by weight, with respect to the total weight of said thermoplastic copolymer, and at least one monomer having general formula (I) wherein: R1 and R2, equal to or different from each other, represent a hydrogen atom; or they are selected from C1-C20, preferably C1-C15, linear or branched alkyl groups, C2-C20, preferably C2-Ci5, linear or branched alkenyl groups, C2-C20, preferably C2-C15, linear or branched alkylidene groups; or R1 and R2, may optionally be bound to one another so as to form, together with the other atoms to which they are bound, a cycloalkene containing from 4 to 6 carbon atoms, saturated, unsaturated, or aromatic, optionally substituted with C1-C20, preferably C1-C15, linear or branched alkyl groups, said cycle optionally containing heteroatoms such as, for example, oxygen, sulphur, nitrogen, silicon, phosphorus, selenium; sai
