Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] This invention relates to modified, acrylate polymer compositions featuring reduced brittleness, such polymers being particularly suitable as dental / medical cements and restorative materials and for manufacturing dental prosthetics.

[0003] 2. Description of the Related Art

[0004] Polymeric materials based on the esters of methacrylic acid have found widespread industrial and medical applications. Their role is particularly prominent in dentistry where they have become a base for modern restorative materials, cements, varnishes, cavity liners and sealers. In medicine perhaps the most important uses of acrylic resins include contact lenses and cements used for hip restorations.

[0005] Many of these applications require the material to meet a combination of requirements with respect to their chemical, optical and mechanical properties and, frequently, biological compatibility. While acrylic resins, due to a variety of ...
