Title
(EN) METHACRYLATE MONOMER-BASED COMPOSITION
(FR) COMPOSITION A BASE DE MONOMERE METHACRYLATE
Abstract
(EN)
The application relates to a two-component composition comprising: - a composition A comprising: - at least one polyurethane P having at least two terminal methacrylate functions, the polyurethane content P being at least 6% by weight relative to the total weight of composition A; - at least one reducing agent; and - at least one methacrylate monomer; - a composition B comprising: - at least one oxidizing agent; and - optionally at least one methacrylate monomer, said polyurethane P being obtained by a method comprising: - E1) a step of preparing an NCO-terminated polyurethane, comprising the polyaddition reaction between: -i) at least one polyisocyanate; and -ii) at least one polyol; - E2) reacting the product formed at the end of step E1) with at least one methacrylate monomer M having at least one hydroxyl function.
