DIMER ACID-DERIVED DIMETHACRYLATES AND USE IN DENTAL RESTORATIVE COMPOSITIONS

Document Type and Number:

WIPO Patent Application WO/2005/107626

Kind Code:

A1

Abstract:

The present invention provides polymerizable dental compositions comprising a dimer acid-derived monomer such as a dimer acid-derived di(meth)acrylate monomer. In one embodiment, the dimer acid-derived monomer is of the formula (I): wherein R₁, R₂, R₃, R₄, R₅ and R₆are independently selected from H and optionally substituted C₁-C₂₅ straight-chained or branched aliphatic, optionally containing 1 or more double or triple bonds, wherein one or more carbons are optionally replaced by R* wherein R* is -C(O)-, -C(O)C(O)-, -C(O)NR⁷-, -C(O)NR⁷NR⁸-, -C(O)O-, -OC(O)-, -NR⁷CO₂-, -O-, -NR⁷C(O)NR⁸-, -OC(O)NR⁷-, -NR⁷NR⁸-, -NR⁷C(O)-, -NR⁷C(O)O-, -S-, -SO-, -SO₂-, -NR⁷-, -SO₂NR⁷- or -NR⁷SO₂-, where R⁷ and R⁸ are independently selected from H and optionally substituted aliphatic, cycloalkyl, heterocycloalkyl, aryl or heteroaryl; provided that at least two of R₁, R₂, R₃, R₄, R₅ and R₆are substituted C_1-25 straight-chained or branched aliphatic wherein at least one carbon is replaced by R* and at least one of the substituents is an alkenyl group.
