Additional information

The QSAR calculated rate constant for the OH sensitized photodegradation of Cyclohexane, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethyl-, homopolymer, caprolactam-blocked (surrogate: blocked trimer) is approximately 112.1E-12 cm3/(molecule * s). At 500,000 OH radicals / cm3 (typical for central Europe), this corresponds to a half-life of 3.4 hours. Hydrolysis is very slow under environmental conditions (half-life > 1 year).
