Unsaturated Polyester Resin Modified With Nylon 66 Oligomers

Abstract Nylon 6, 6 oligomers, obtained from industrial wastes, were used for modifying an unsaturated polyester resin, creating a series of semi-interpenetrating polymer networks (semi-IPN's) with different compositions. The oligomer was dissolved in the resin by heating. Then, the modified polyester was crosslinked at room temperature. The tensile strength, impact strength and thermal properties of the prepared semi-IPN's are reported. A relationship between the mechanical properties and thermal characterization with the developed morphology of the semi-IPN's was established.
