Abstract
The molecular association complexes of aliphatic 6,n-ionenes: –[––(–CH2–)–6—N⊕(CH3)2Br⊖—–(–CH2–)–n—N⊕(CH3)2Br⊖–]–p—, n=3, 4, 5, 6, and 10; with thiourea were obtained. Their elemental analyses were consistent with association of only one molecule of thiourea per quaternary ammonium nitrogen site. The IR spectra of the ionene complexes resembled the spectrum of the noninclusion-type 2: 1 thiourea complex of hexamethylene-bis(cetyldimethylammonium) dibromide rather than that of the well-defined thiourea inclusion compound of cetyltrimethylammonium bromide. The IR band at 710—730 cm−1 turned out to be useful in distinguishing the ionic noninclusion-type thiourea complexes from the inclusion compounds. The melting temperatures measured by DSC lay between 130°C and 150°C. A typical even-odd alternation was recognized: when n was even, the melting temperature of a complex was higher by ca. 10°C than when n was odd.
