Description
Verfahren zur Herstellung von Kunststoffen Es wurde gefunden, daß cyclische Anhydro-ce-oxyalkyl-carbamidsäuren (cyclische Urethane) mit mindestens sieben Ringgliedern zu technisch wertvollen Kunststoffen polymerisiert werden können. Die Polymerisation kann leicht in an sich bekannter Weise, so z. B. durch Erhitzen der cyclischen Urethane in der Schmelze oder gegebenenfalls in Gegenwart eines Lösungsmittels, durchgeführt werden.Process for the manufacture of plastics It has been found that cyclic anhydro-ce-oxyalkyl-carbamic acids (cyclic urethanes) with at least seven ring links can be polymerized into technically valuable plastics. The polymerization can easily be carried out in a manner known per se, e.g. B. by heating the cyclic urethanes in the melt or, if appropriate, in the presence of a solvent, be performed.
Unter den cyclischen Urethanen, die nach dem vorliegenden Verfahren durch Polymerisation in Kunststoffe übergeführt werden können, seien z. B. die nach einem bereits vorgeschlagenen Verfahren erhältlichen Anhydroverbindungen von Carbamidsäuren genannt, die sich von den folgenden Aminoalkoholen ableiten: Butanolamin-i, q., 2-Methylbutanolamin-i, q., Pentanolamin-1, 5, Dodekanolamin-i, i2, o-Oxyphenyläthylamin, co-Aminopropyl-co'-oxydecyläther. Als Lösungsmittel eignen sich z. B. Tetrachloräthan, Benzin, Benzol, Toluol, Xylol und Phenol.Among the cyclic urethanes produced by the present process can be converted into plastics by polymerization, such as: B. the after anhydrous compounds of carbamic acids obtainable from an already proposed process called, which are derived from the following amino alcohols: butanolamine-i, q., 2-methylbutanolamine-i, q., Pentanolamine-1, 5, dodecanolamine-i, i2, o-oxyphenylethylamine, co-aminopropyl-co'-oxydecyl ether. Suitable solvents are, for. B. tetrachloroethane, Gasoline, benzene, toluene, xylene and phenol.
Beispiel i Anhydro-(co-oxybutyl)-carbamidsäure wird unter Stickstoffatmosphäre auf i75° erhitzt. Nach 5 bis io Minuten wird die Schmelze innerhalb weniger Minuten hochviskos und erstarrt beim Abkühlen zu einer weißen, hornartigen Masse von einem Schmelzbereich zwischen i7o und 175°. Die Masse ist löslich in Kresol und Ameisensäure. Sie kann z. B. zu Fasern, Preßmassen oder Spritzgußmassen verarbeitet werden. Beispiel 2 Anhydro-(3-methy1-4-oxybutyl)-carbamidsäure wird unter Stickstoffatmosphäre auf 17o° erhitzt. Die Schmelze wird nach i Stunde hochviskos und erstarrt beim Abkühlen zu einer knetbaren Masse. Die Masse ist löslich in Kresol, Ameisensäure sowie in einem Gemisch von 8o Gewichtsteilen Methanol und 2o Teilen Wasser. Sie kann z. B. zur Herstellung von Präparationsmitteln auf dem Textilgebiet verwendet werden.Example i Anhydro (co-oxybutyl) carbamic acid is produced under a nitrogen atmosphere heated to 175 °. After 5 to 10 minutes, the melt becomes melt within a few minutes highly viscous and solidifies on cooling to a white, horn-like mass of one Melting range between i7o and 175 °. The mass is soluble in cresol and formic acid. You can z. B. processed into fibers, molding compounds or injection molding compounds. example 2 Anhydro- (3-methy1-4-oxybutyl) -carbamic acid is generated under a nitrogen atmosphere Heated to 17o °. The melt becomes highly viscous and solidifies after 1 hour at the Cool to a kneadable mass. The mass is soluble in cresol, formic acid and in a mixture of 80 parts by weight of methanol and 20 parts of water. she can e.g. B. used for the production of spin finish in the textile field will.
