Production of thermoplastically processable compound material from natural duroplastic products such as chitin, keratin or casein involves treatment with weak acid to form short-chain thermoplastic polymer.

Abstract
Ein Verfahren zur Herstellung eines thermoplastisch verarbeitbaren Compound-Werkstoffs aus natuerlichen Polymeren sieht vor, dass langkettige natuerliche Polymere mit ueberwiegend duroplastischen Materialeigenschaften durch eine chemische Behandlung mit schwachen Saeuren zu kurzkettigen Polymeren mit ueberwiegend thermoplastischen Materialeigenschaften gespalten werden. Ein derartiger Compound-Werkstoff kann zu thermoplastisch verarbeitbaren Naturstoffgranulaten weiterverarbeitet werden.

 

EP 1000953 A UPAB: 20000630 NOVELTY - A process for the production of a thermoplastically processable compound material from natural products, in which long-chain natural products with mainly duroplastic properties are subjected to chemical treatment with weak acids to give short-chain polymers with mainly thermoplastic properties. USE - For the production of thermoplastic material. ADVANTAGE - A low-cost process for the production of thermoplastically processable compound material from natural polymers with essentially non-thermoplastic properties, e.g. inexpensive waste products such as chitin and keratin.
