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 R6 are 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 R6 are substituted C1-25 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.
