    摘要: The resin comprises oligomers of naphthalic acid groups bridged by substantially only keto groups, the oligomers being joined together with a di- or tetra-functional primary aromatic amine and having been derived from a resin produced by acid-catalysed condensation of acenaphthene and a formaldehyde donor.
    It is envisaged that the resin will be of use in the preparation of drogue parachutes and in other circumstances where a thermally stable resin is required.

    摘要: This invention relates to an improved poly-(amide-imide) resin, a process for its preparation and its use as a temperature resistant resin.
    According to the present invention, there is provided an improved method of producing a poly-(amide-imide) resin comprising the steps of;

    (1) reacting a phenanthrene with formaldehyde or a formaldehyde donor in the presence of an acid catalyst to give a phenanthreneformaldehyde reaction product having substantially only methylene bridges;
    (2) removing from the reaction product unreacted phenanthrene;
    (3) treating the reaction product with formaldehyde or a formaldehyde donor in the presence of an acid catalyst to give a high molecular weight product having substantially only methylene bridges;
    (4) oxidising the high molecular weight product to break the 9, 10 bond in the phenanthrene moieties to produce a polycarboxylated reaction product;
    (5) reacting the polycarboxylated reaction product with an aromatic diamine to produce a poly-(amide-imide) resin.

    The resin would find use as a lamp capping cement, as a high temperature insulator, in copper clad high temperature printed circuits, in electrical heater panels, in transformers and in glass or asbestos laminates for use as compressor blades.

    摘要: A hydrotreating catalyst which is resistant to carbonaceous deposits and is particularly useful for hydrotreating coal-derived liquids, is molybdenum or tungsten disulphide in an amount of 0.1 to 10% by weight, substantially completely on the outer surface of an active carbon support having a surface area in excess of 800 m 2 /g. The catalyst can be made by absorbing molybdenum or tungsten trisulphide onto the active carbon support and reducing the trisulphide to the disulphide.
