Definitions

  • the present invention relates to a copolymer, a polymer mixture comprising such a copolymer, a process for producing such a copolymer and the use of such a copolymer.
  • thermoplastic polymers usually have inadequate mechanical properties for certain applications, in particular at elevated temperatures and under the influence of media such as fuel, engine oil and brake fluid.
  • media such as fuel, engine oil and brake fluid.
  • rigidity in combination with high tensile strength and fatigue strength is often insufficient.
  • Certain glass fiber reinforced polyamides may have high tensile strength in the machine direction (flow direction), but such materials are often anisotropic and lack sufficient transverse strength (flow direction) strength.
  • Polyphenylenes can have high mechanical strengths and stiffnesses. Some polyphenylenes are for example in the documents US
  • polyphenylenes may be soluble in a number of solvents, which may result in limited media resistance to fuel, engine oil and similar media. Disclosure of the invention
  • the present invention is a copolymer, in particular a block copolymer, prepared by reacting a polyphenylene having two, each terminal coupling groups X 1 and X 2 with a flexible chain component, which has a flexible chain with two, respectively terminal coupling groups Y 1 and Y 2 , wherein according to the invention each one of the coupling groups X 1 and X 2 with one of the coupling groups Y 1 and Y 2 under training fertil a bond selected from the group consisting of carboxamides mid-binding (also amide bond mentioned), Carbonklareester bond (also called ester bond), carboxylic acid imide bond (also called imide bond), urethane bond, carbonate bond, urea bond, thiourea bond, sulfonic acid amide bond (also called sulfonamide bond), sulfonic acid ester bond (also called sulfone ester bond), imidazole bond,
  • the carboxylic acid imide bond may be a phthalimide bond and / or the imidazole bond may be a benzimidazole bond and / or the oxazole bond may be a benzoxazole bond and / or the thiazole bond to act as a benzothiazole bond.
  • bonds mentioned above are understood in particular to mean bonds according to the following structural formulas, where R ', R'a, R'b, R'c or R'd on the one hand and R "on the other hand stand for the polyphenylene or the flexible chain, where R '"and R" "stand for hydrogen, another substituent or for another area of the polyphenylene or the flexible chain.
  • Such copolymers may advantageously have improved media resistance to fuel, engine oil and similar media.
  • such copolymers may advantageously have high intrinsic stiffness. This has the advantage that the copolymers according to the invention in the vehicle sector can also be used for media-contacting components.
  • such copolymers can advantageously be processed thermoplastically. By the polyphenylene advantageously a high rigidity can be ensured. Due to the flexible chain component, the processing temperature can advantageously be set to a greater distance from the decomposition temperature.
  • a "flexible chain” is understood as meaning, in particular, a chain comprising carbon atoms and optionally heteroatoms, which comprises at least one, at least partially rotatable, single bond

Abstract

L'invention concerne un copolymère fabriqué par transformation d'un polyphénylène comportant deux groupes de couplage X1 et X2 respectivement terminaux, et d'un composant de chaîne flexible comprenant une chaîne flexible comportant deux groupes de couplage Y1 et Y2 respectivement terminaux. Un module d'élasticité élevé, une grande résistance aux milieux et une fabrication économique à grande échelle peuvent être obtenus du fait que la chaîne flexible présente une longueur inférieure ou égale à 95 atomes de chaîne, et respectivement un groupe de couplage X1 ou X2 réagit avec un groupe de couplage Y1 ou Y2 de manière à former une liaison choisie dans le groupe composé des liaisons suivantes: amide d'acide carboxylique, ester d'acide carboxylique, imide d'acide carboxylique, uréthane, carbonate, urée, thiourée, amide d'acide sulfonique, ester d'acide sulfonique, imidazole, oxazole, thiazole, oxazoline, imidazoline, amine, éther et thioéther.
