| titleOfInvention | PROCESS FOR INCREASING THE MOLAR MASS OF POLYAMIDES WITH ESTER CATALYSTS OR ORGANOPHOSPHONIC ACID OR IN THE PRESENCE OF TITANIUM DIOXIDE CONTAINING ALUMINUM OXIDE. |
| abstract | Process for increasing the molar mass of a polyamide in the presence of titanium dioxide containing aluminum oxide. In this process, a polyamide containing terminal carboxylic and amino groups, and titanium dioxide containing aluminum oxide, are heated in the presence of a catalytically effective amount of at least one phosphonic acid catalyst. and/or an ester of the latter selected from: R(CH2)nPO3R12 where: R represents 2-pyridyl or 2-methoxyphenyl; each R1 is independently selected from H or C1-10 alkyl; and n represents 0 or an integer between 2 and 5 provided that n is 0 when R represents 2-methoxyphenyl. |
