Abstract
The properties of liquid crystalline (LC) oligomers produced from 2-thioalkoxyhydroquinones (2-thioalkoxyHQs) and 2-alkoxyhydroquinones (2-alkoxyHQs) with terephthaloyl chloride (1a–c, 2a–c) have been studied and their compatibility with polyamide 11 (PA 11) has been investigated. FTIR studies showed two conformations of the synthesized oligomers. A three-point bending test indicated that oligomeric chains could strengthen the final flexural properties of the polyamide. Strength of PA 11 was increased by addition of only 1% of LC oligomers to the matrix. Compatibility between oligomer chains and PA 11 was lower than the compatibility between corresponding oligomers of 2-alkoxy-4-hydroxybenzoic acids (2-alkoxyHBAs) and PA 11.
