Abstract
A foam material made from a composition [composition (C)] comprising at least one high temperature poly(aryl ether sulfone) (PAESHT) polymer characterized in that the PAES polymer comprises from 1 to 99% by weight amount of at least one recurring unit (RPAES) [(RPAES−1)]) based on the total amount of recurring units, and from 1 to 99% by weight amount of at least one recurring unit (RPAES) [(RPAES−2)], based on the total amount of recurring units, and wherein said (RPAES−2) recurring unit is different from the (RPAES−1) recurring unit.
