Description of key information

The hydrolysis behaviour of Benzenediamine, ar-methyl-, polymer with 2-methyloxirane and oxirane was investigated at pH = 4, 7 and 9 using a HPLC/MS methods for analysis. Diaminotoluene, ethoxylated and propoxylated, as an NLP, contains different molecular weight fractions (= NLP-fraction) which behave similar in hydrolysis reaction. Benzenediamine, ar-methyl-, polymer with 2-methyloxirane and oxirane is found to be stable at 50°C with less than 10 % dissipation in 5 days at all three pH-values. Therefore, it can be assumed that the test item is also stable at 25°C and no half-life times and hydrolysis rates were calculated (Currenta, 2009).
