Description / Table of Contents:
Ionische Polyester mit ziemlich niedrigen Molekulargewichten wurden dargestellt durch Polyumesterung von 1,1′-Bis(carbäthoxy)kobalticiniumhexafluorphosphat (1a) und den Diolen 1,10-Decandiol bzw. 1,4-Bis(hydroxymethyl)benzol in der Schmelze. Versuche Polyamide durch Schmelzkondensation aus Alkylendiammonium-Salzen des 1,1′-Bis(carboxy)kobalticiniumhexafluorphosphats darzustellen, führten zu weitgehender Zersetzung. Die Polyester wurden durch Analysen, IR-Spektroskopie, Gelchromatographie und Differentialkalorimetrie charakterisiert.
Notes:
Ionic polyesters of fairly low molecular weights were prepared by melt phase polytransesterification of 1,1′-bis(carbethoxy)cobalticinium hexafluorophosphate (1a) and diols such as 1,10-decanediol and 1,4-bis(hydroxymethyl)benzene. Attempts to prepare polyamides by melt condensation from alkylene diammonium salts of 1,1′-bis(carboxy)cobalticinium hexafluorophosphate 5a-d resulted in extensive decomposition, and pure polyamides could not be obtained. The polyesters were characterized by analyses, IR spectroscopy, gel permeation chromatography, and differential scanning calorimetry.
