Abstract
Dimethacrylates are provided having the following chemical structure: ##STR1## wherein n represents a number of 2 to 8; PA1 R.sub.1 and R.sub.2 are the same or different and are hydrogen or groups of the formula: ##STR2## where R.sub.3 is an aliphatic, aromatic or cycloaliphatic group having 1 to 14 carbon atoms. These compounds are useful in dental material which cures to form polymers having high mechanical strength, low water sorption, resistance to staining, good color stability when exposed to short-wave radiation (e.g., sunlight) and good chemical resistance to the oral environment. Also provided are a method for polymerizing these compounds in situ on teeth and a tooth comprising polymers of these compounds.
