| titleOfInvention | High molecular weight copolyamides containing quinazoline dione units |
| abstract | High molecular weight aromatic copolyamides which contain a small proportion of structural units having 2,3-(1H,3H)-quinazoline dione rings are disclosed. The presence of quinazolinedione ring units in the copolyamide results in an increased moisture absorption capacity. By using small amounts of quinazoline dione units, the good physical properties of the corresponding quinazoline dione-free polyamide are substantially retained while the moisture absorption is significantly increased. Larger amounts of quinazoline dione units than contemplated (15 mol percent and more) do not improve the moisture absorption further and adversely affect the physical properties. The copolyamides are useful in textile applications in which the improved moisture absorption serves to make clothing prepared from such textiles more comfortable. |
