Adducts of 3-methacroyl-2-hydroxypropyl esters with diisocyanates

Abstract

Dimethacrylates are provided having the following chemical structure: ##STR1## where R.sub.1 and R.sub.2 may be the same or different and are cyclohexyl or phenyl groups which may be substituted or unsubstituted; and R.sub.3 is an aliphatic cycloaliphatic or aromatic group having 6 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.

Dependencies are inferred from the claim text.
