2. REACH provisions for polymers and related monomers

Due to the potentially large number of different polymer substances on the market, and given that polymer molecules are generally considered to present a low risk due to their high molecular weight, this group of substances is currently exempt from registration and evaluation under REACH, although some polymers may be subject to authorization and restriction. However, polymer manufacturers and importers may be required to register monomers or other substances used as basic components of the polymer, as these molecules are generally considered to present a higher risk than the polymer molecule itself.
