摘要
The subject matter of the invention is an autopolymerisable 2-component prosthetic base material, a kit containing the material as well as a method for its production comprising at least one liquid monomer component (A), and at least one powdered component (B), wherein the prosthetic material in component (A) besides methylmethacrylate contains at least one N-alkyl-substituted acryloyloxy carbamate having a molecular mass of less than or equal to 250 g/mol, optionally at least one at least di-functional urethane (meth)acrylate, a di-, tri-, tetra- or multi-functional monomer not being urethane (meth)acrylate, and optionally polymeric particles having a primary particle size of less than 800 nm, and the powdered component (B) comprises polymeric particles having at least three different particle size fractions, and both (A) and (B) contains at least one initiator or at least one component of an initiator system for autopolymerisation.
