Abstract (en)

[origin: WO2014174176A1] The present invention relates to a composition including, by weight, the total being 100 %: 50 to 99 % of a curable resin and of a curing agent in a molar ratio in the range of 1/5 to 5/1, and 1 to 50 % of a mixture: of a polyamide which includes at least one monomer resulting from the condensation of a diacid and of a diamine of formula (1) where: R1 is H or -Z1-NH2 and Z1 is an alkyl, a cycloalkyl or an aryl having up to 15 carbon atoms, and R2 is H or -Z2-NH2 and Z2 is an alkyl, a cycloalkyl or an aryl having up to 15 carbon atoms, R1 and R2 being either identical or different, and of an oligomer made from butadiene and acrylonitrile which are terminated by carboxyl functions or by amine functions, such as the reactive rubbers CTBN or ATBN; the polyamide and the oligomer being present in respective proportions of 1/10 to 10/1 by weight.
