Marginal adaptation of dental composites containing prepolymerized filler.
Operative dentistry, 1998Marginal adaptation to cylindrical dentin preparations of five commercially available dental composites--Charisma, Estelite, Herculite, Pertac, and Silux Plus--and seven experimental dental composites containing prepolymerized filler was evaluated by measurement of the wall-to-wall polymerization contraction gaps.

Studies on the rheological behavior of high‐impact polystyrene prepolymerizing systems
Journal of Applied Polymer Science, 1986AbstractThe rheological behavior of high‐impact polystyrene prepolymer and its two phases separated by ultracentrifugation was studied. The viscosities of prepolymer, polystyrene phase, and rubber phase were correlated with various parameters, and a quantitative relationship among these three viscosities was proposed.

Poly(hydroxyethyl methacrylate)/silica (PHEMA/SiO2) hybrid organic–inorganic nanocomposites were prepared through the simultaneous polymerization of 2-hydroxyethyl methacrylate and tetraethoxysilane. PHEMA/SiO2 materials were obtained as monolithic and transparent films consisting of silica nanoparticles (diameter below 100 nm) surrounded by the PHEMA ...

Prepolymerization of Gluma 4 sealer: effect on bonding.
American journal of dentistry, 1990This study evaluated the effect on microleakage of placing a composite resin over either cured or uncured Gluma 4 sealer. Class V preparations were placed at the cemento-enamel junction of extracted human molars. Herculite XR was used to restore cavities that had been pretreated with Gluma bonding system with the sealer being either uncured or cured ...
