Abstract: A polymer comprising repeating units derived from a first monomer, typically acrylonitrile, and repeating units derived from a second monomer different from the first monomer, wherein the second monomer is a compound comprising an ethylenically unsaturated organic anion and an organic cation containing a C═N imine group; a process for producing carbon fibers using the said polymer; and carbon fibers made therefrom, are described herein.

Abstract: A fiber-reinforced polymeric composite structure having chemically active thermoset particles positioned in an interlaminar region between adjacent layers of reinforcement fibers and method of making the same. Upon curing of the composite structure, the chemically active functional groups on the thermoset particles form covalent bonds with the matrix resin surrounding the particles. In one embodiment, the particles are formed of a partially cured thermoset polymer with a degree of cure of less than 100%. In another embodiment, the particles are derived from a thermosettable resin composition, wherein the stoichiometry is such that there is a deficiency or an excess in the amount of curing agent that is necessary for reacting with 100% of the thermoset resin component. In some embodiments, the composition of the chemically active thermoset particles is the same or substantially the same as that of the matrix resin of the composite structure.
