The invention relates to a sulfone polymer composition comprising: at least one high glass transition temperature sulfone polymer [polymer (A)]at least one highly tough sulfone polymer [polymer (B)] with the exception of: a sulfone polymer composition composed of 50% wt of polybiphenyldisulfone, namely a homopolymer the recurring units thereof are recurring units (R1) and 50% wt of polyphenylsulfone, namely a homopolymer the recurring units thereof are recurring units (R3): and a sulfone polymer composition composed of 30% wt of a polymer 75% mol of the recurring units thereof are recurring units (R1) and 25% mol of the recurring units thereof are recurring units (iii) and 70% wt of polyphenylsulfone. The sulfone polymer composition of the invention possesses advantageously thermal performances and toughness advantages in addition to minor cost with respect to high glass transition sulfone polymers.
