摘要：
A hardenable epoxy resin composition comprising a curable epoxy resin, a hardener for the epoxy resin and a polyetherimide having the general formula;
where
X is CyH 2 y, or
, or -S-
y is a positive integer from 1 to 5
m is 0 or 1
n is a positive integer from 20 to 150 and
R' is an aromatic hydrocarbon radical having from 6 to 20 carbon atoms, or a cycloalkylene radical having from 2 to 20 carbon atoms or a divalent radical of the formula
where
and
x is a positive integer from 1 to 5. Preferably X is C 3 H 6 and R' is preferably
The compositions are particularly suitable for use in fibre composite materials.
