Abstract
A method increases the toughness of a material obtained by curing a composition that includes at least one vinyl ester monomer. The method includes the incorporation into the composition of a sulfonated polyaromatic thermoplastic polymer, which is achieved by dissolving the vinyl ester monomer and the thermoplastic polymer in a reactive diluent in which they are both soluble. The resulting curable composition includes at least one vinyl ester monomer, and very high toughness materials can be made from it. A curable composition can include at least one vinyl ester monomer, a sulfonated polyaromatic thermoplastic polymer and a N-vinyl lactam. The compositions can be used in the aeronautical, space, railway, nautical, automotive industries, arms and other industries.
