  • Patent number: 5446096
    Abstract: Blends of an aromatic polysulfone (PSF) and aromatic alkyl methacrylates (PAAM) form thermodynamically miscible mixtures. They exhibit only one glass transition over a wide range of compositions and show marked improvement in mechanical and thermal properties compared to binary mixtures of PSF and other methacrylate or styrenic polymers. Furthermore, they possess better processing and workability without unwanted thermal decomposition owing to better flow properties at relatively lower temperatures.
