Abstract
Oligomers of highly purified methacryl substituted silanes, e.g., methacryloxyalkyltrialkoxysilanes, can be combined with (meth)acrylate monomers to give viscosities in a range such that they can be heavily filled for use in dental filling compositions. They can remain stable for extended times in contact with catalyst until initiated and are of particular value in two part dental filling systems.
