Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
The maximum estimated dissipation half-life time for components of DVB-55, -65, and -HP is 6.3 hours, which represents that for reaction with both hydroxyl radical and ozone in the troposphere. While the substance may absorb sunlight at wavelengths > 290 nm, there exists no experimental evidence to suggest that direct photolysis in air, water, or soil is an important fate process for the components of this substance. Divinylbenzene is stable at 25°C and 49-51°C and at pH 4, 7 and 9 in water over 5 days, indicating that hydrolysis is not an important process affecting the fate of this substance/components in the aquatic environment. Biodegradation is expected to be the most important process affecting fate/lifetime of the DVB substance components in water, soil, and sediment. Although the biodegradation screening tests indicate little or no biodegradation of these substances, their analogy to other biodegradable alky-substituted aromatics (e.g., styrene, ethylbenzene, toluene, xylenes) whose metabolic pathways are well-known and documented, indicates that the components of the DVB substance will be ultimately biodegradable in the environment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
