| titleOfInvention | Process for purifying a copolymer containing acrylonitrile groups |
| abstract | The invention relates to a process for purifying a copolymer containing acrylonitrile groups, by treating the copolymer per kg impurities of the copolymer, with at least 1 Nm 3 (NPT) of an extractant chosen from substances the critical temperature of which is lower than 435 K, at a temperature higher than 0.9 time the critical temperature of the extractant and a pressure higher than 0.9 time the critical pressure of the extractant. n A major advantage of the process according to the invention is the substantial improvement of the heat distortion temperature (HDT) of the purified copolymer containing acrylonitrile groups compared with the HDT of the copolymer containing acrylonitrile groups before the purification. |
