New Monomers

Development of new bone cement utilizing low toxicity monomers.

Acrylic bone cement is self-curing cement comprising of liquid and powder component of methyl methacrylate (MMA). It has been used extensively in orthopedics; however, adverse effects were associated with its use. Hence we investigated in this paper the possibility of new cement utilizing methacrylates with lower toxicity than MMA. LD50s of candidate monomers were determined with administration...

New bis-urea cross-linking monomers as effective oxyanion receptors

A library of new polymerizable functional cross-linking monomers designed for complexation with the oxyanionic moiety of the chemotherapeutic drug methotrexate (MTX). The H NMR binding study of a variety of synthetic receptors and the compilation of the obtained results lead to the identification of monomers combining interactive functionality and a cross-linking format, specific binding recept...

Containing Adhesion Promoting Monomers

Preeious metal alloys bondcd by the adhesive r'esin were thermocycled O, 1,OOO, 2,OOO, or 4,OOO times in water between 4 and 60°C , and tensile bend strengths were measurecl. Debonded metal surfaces after the tensile test were analyzed based on an area of cohcsive failure. Three-way ANOVA revealed that all the three parameters adherend, adhesive rnonemer, and nurnber of thermal cycles exhibited...
