| titleOfInvention |
Method for the manufacture of poly(aryl ether ketone)s in the presence of sodium carbonate |
| abstract |
The present invention relates to sodium carbonate (Na2CO3) having a certain particle size distribution and its use in preparing poly(aryl ether ketone)s, especially PEEK. Poly(aryl ether ketone)s made using the described sodium carbonate also make up a part of the invention. The present invention relates also to a method for providing a sodium carbonate having a certain particle size distribution, which is especially well suited for the preparation of poly(aryl ether ketone)s. |
