Influence of polymerization conditions on monomer elution and microhardness of autopolymerized polymethyl methacrylate resin
. Eur J Oral Sci 2002; 110: 179-83.
Different matrices, among which epoxy resin, methacrylate resin
and a proprietary composite resin are used by manufacturers.
Peroxide cure systems are frequently used for curing roll compounds because of: the ease of increasing hardness by increasing the level of methacrylate resin
coagents; and because they give the best heat aging characteristics.
EndoRez is a methacrylate resin
with hydrophilic properties .
Degussa Corp., Ridgefield Park, N.J., will describe how RTM tools can be produced quickly and easily by mass casting the company's Atlas M130 system of thermosetting methacrylate resin
filled with 85% aluminum powder and granules, a system that has already proven successful in RIM tools.

Adhesion between two different restorative materials and to the same restorative material itself should be of practical attention.10 Silorane based composite resin system as recommended by manufacturers is chemically incompatible for use with methacrylate based composites.14 Thus most of the authors have done the repair of original composite substrate with the same composite.7,15 As siloxanes based composite resin requires different method for activation, commonly used Bis-GMA based adhesives are not compatible for use with silorane based composite resin and the bond between methacrylate resins
and silorane resins is not as strong as those with the same material.
But water storage of denture base acrylic resins can lead to reduction of residual methyl methacrylate resins
by diffusion into water.24 Therefore, it is suggested that one of the methods for reducing the monomer release is storing the denture and acrylic appliance in water for 24 hours before insertion in patients' mouth.
