Abstract
New medical self-polymerizable sealing cement with an acrylic polymer and/or copolymer base, applicable for prosthetic implants, which is obtained by mixing a liquid phase and a solid phase. The liquid phase, being viscous, forms a collodion of an acrylic polymer and/or copolymer in at least one monomer, while the solid phase is composed of an acrylic polymer and/or copolymer possibly containing a mineral load. The new cement is not dangerous for the patient, due to an absence of monomer exudation and due to a polymerization temperature which is always lower than the mobilization temperature of human fat.
