Abstract
A crosslinked aramid polymer comprising a first aramid backbone which is crosslinked through a poly(meth)acrylic acid with a second aramid backbone. The crosslinked aramid polymer is obtained by polymerizing a monomeric aromatic diamine with a monomeric aromatic diacid, or halide or ester thereof in the presence of poly(meth)acrylic acid, followed by a curing step. The crosslinked aramid polymer is crosslinked through its amide bonds and can be made to a fiber, film or fibrid.
