PPOÒ SA120 resin is a new low molecular weight (Mn »2500) polyphenylene-ether (PPE) resin recently commercialized by GE Plastics. In addition to having the well-known properties inherent to PPE, this new resin has an excellent thermal performance (glass transition temperature (Tg) of 165°C) combined with a characteristic feature of improved processability. Replacing the hydroxyl group on SA120 with a reactive methacrylate forms the developmental product PPOÒMX5587 resin. PPOÒMX5587 resin can be used as the building block for films, RCC, adhesives, laminates and many others. Thermosettable NorylÒ resin is a hybrid material that bridges the performance gap between thermoplastics and thermosets. Depending on the filler type and loading, Thermosettable NorylÒ resin can be used in applications such as fuel cell conductive plates, automotive-electrical applications, super-abrasive grinding wheels, aerospace and high performance composites, automotive body panels, truck boxes, electrical insulation, microchip encapsulants, printed circuit boards, etc. The data show that compositions containing PPOÒMX5587 resin would have improved fracture toughness, higher heat resistance, better dielectric properties, and lower moisture uptake compared to unsaturated polyester resins and vinyl ester resins. In addition to PPOÒMX5587 resin which has an intrinsic viscosity (IV) of 0.12 dl/g, other vinyl capped PPE resins such as 0.15 IV and 0.25 IV can be tailored to meet specific requirements.
