Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 test substance is a monomer that is further bound in a polymer. The unreacted monomer is a gas under environmental conditions. It has a high vapour pressure (1.71E6 Pa) and Henry's Law constant (8371.7 Pa m3/mol), and low Log Kow (0.90) and Koc (21.7 L/kg). Consequently, if any environmental releases occur, the test substance will compartmentalize into the atmosphere. Given the conditions of use, environmental levels of the test substance are likely to be insignificant as the monomer is bound in a polymer. The water solubility of the test substance suggests that atmospheric deposition to land and water could occur, however due to its volatility and low sorption to soil, this would likely result in rapid redistribution from both soil and water to air.
The test substance is stable to hydrolysis and is not readily biodegradable. However, the atmospheric half-life versus reaction with the hydroxyl radicals is 2.9 days, while reaction with ozone is minimal (DT50 >3 months).
The substance properties, including high vapour pressure and a log Kow < 3.0, and use limits both direct and indirect exposure potential for aquatic and terrestrial organisms. Thus, the test substance can be expected to have low potential for bioaccumulation in aquatic and terrestrial organisms.
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.
