Abstract: Fibrids are prepared by introducing a solution of a polymer into a liquid precipitation medium while exposing it to shearing forces. A poly(amide-imide) resin solution is admixed with a solvent which is miscible with the resin solvent but which is a non-solvent for the resin itself.

Abstract: The invention relates to polyethylene terephthalate moulding compositions which are stabilised against degradation of the molecular weight during the processing in the melt. They contain a stabilising mixture of a) a tetracarboxylic dianhydride, preferably pyromellitic dianhydride, b) an aryl carboxylate, preferably diphenyl carboxylate, and c) a diglycidyl ether, preferably of bisphenol-A. The moulding compositions can be used to produce injection mouldings.

Abstract: The manufacture of paper-like and textile-like sheet materials by the use of fibrids which have been obtained by dissolving poly(amide-imide) resins in an organic solvent, mixing the resulting solution with a liquid which is a non-solvent for the polymer and introducing the resulting solution into a liquid precipitation medium while exposing it to shearing forces.

Abstract: Dicarbonyl chlorides (I) contg. imide gps. are produced by (a) suspending trimellitic anhydride (II) and aromatic diamines (III) of the formula H2N.C6H4.X.C6H4.NH2) (in which X is CH2, 0, S, SO2 or CO; the NH2 gps. can be in the o-, m- or p-position) in a high-boiling inert organic liquid (IV) and reacting to the diimido-dicarboxylic acid (V) and then (b) converting (V) to (I) with SOCL2 or COCL2. High temp. -resistant polymers and pigments are produced by reacting a suspension of (I) in PhNO2, without further purificn., with diphenols, diamines or aminophenols. (I) are obtd. in almost 100% yield and in high purity by a process suitable for technical operation.
