High-impact, transparent denture material with low residual MMA content

摘要

The invention relates to an autopolymerizable 2-component prosthesis base material, a kit containing the material and a method for its preparation comprising at least one liquid monomer component (A), and at least one powdery component (B), wherein the prosthesis material in the component (A) in addition to methyl methacylate, at least one N-alkyl-substituted acryloyloxy carbamate having a molecular weight of less than or equal to 250 g / mol, optionally at least one at least difunctional urethane (meth) acrylate, a di-, tri-, tetra- or multi-functional monomer, which is not a urethane (meth) acrylate, and optionally contains polymeric particles having a primary particle size of less than 800 nm, and the powdery component (B) comprises polymeric particles having at least three different particle size fractions and both (A) and (B) contain at least one initiator or at least one component of an initiator system for autopolymerization.
