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 temperature sulfo ne polymers. |
