“…Some of the more common thermosets include epoxies, polyester, vinyl ester, phenolics, amino resins, bismaleimides, polyimides and polyamides. Unsaturated polyester resins that provide a unique combination of room-temperature processability in the uncured state and hightemperature (200 3 C) stability in the cured state have been the subject of several reports [2][3][4][5][6][7][8]. Polyesters are becoming increasingly popular because of their low cost, ease of use and versatility.…”

An intercrosslinked network of hybrid bismaleimide-modified vinyl ester oligomer-unsaturated polyester matrix systems were developed. Vinyl ester oligomer was used as a toughening agent for unsaturated polyester resin and was added in 10, 20 and 30% (by weight). Benzoyl peroxide was used as curing agent. The vinyl ester oligomer-toughened unsaturated polyester matrix systems were further modified with 5, 10 and 15% (by weight) of bismaleimide. Bismaleimide-modified vinyl esterunsaturated polyester matrices were characterized by mechanical (tensile strength, flexural strength, tensile modulus, flexural modulus and impact strength), thermal [differential scanning calorimetry (DSC) thermogravimetic analysis (TGA) and heat deflection temperature analysis (HDT)] and morphological studies [scanning electron microscope (SEM)] and water absorption. Data obtained from mechanical and thermal studies indicated that the introduction of vinyl ester oligomer into unsaturated polyester resin improved the fracture toughness with marginal reduction in the values of heat deflection temperature and glass transition temperature. The introduction of bismaleimide into vinyl ester oligomer-incorporated unsaturated polyester resin enhanced both thermal and mechanical behavior. The SEM micrographs of fractured surfaces of vinyl ester oligomer modified unsaturated polyester systems and BMI modified vinyl ester-unsaturated polyester matrices illustrate the presence of heterogeneous morphology.

“…Unsaturated polyester resins that provide a unique combination of room‐temperature processability in the uncured state and high‐temperature (>200°C) stability in the cured state have been the subject of several reports 3–9. These resins are mixtures of various compositions of oligomers and difunctional aromatic monomers with styrenic or methacrylic functionality (Fig.…”

ABSTRACT:We describe our investigations of the curing chemistry and properties of heat-resistant thermosets comprised of unsaturated ester resins. We suggest a mechanism for the rearrangement of the cured matrix and volatile evolution during the curing process. We employed dielectric spectroscopy (DES) as a tool for monitoring the extent of cure, determining glass-transition temperatures, and evaluating electrical properties of the resins. We compare and contrast results obtained by DES to results obtained by dynamic mechanical analysis (DMA). Fracture testing showed that improvements were made in the toughness of these materials by blending the uncured resin with impact modifiers such as hydrocarbon or silicone reactive rubber adducts or poly(arylene ether sulfone)-based thermoplastic oligomers. We determined the effects of the thermoplastic toughening additive's molecular weight, concentration, and endgroup functionality on the phase separation, thermal stability, and fracture toughness of the blend.
