New alkenoic acid derivatives can be prepared by reaction of corresponding aldehydic esters with phosphorous compounds in inert solvents and in the presence of bases followed by hydrolysis of the intermediate esters. The new alkenoic acid derivatives can be used as active compounds in medicaments.

A curable composition comprises at least 10 wt % expanding monomers based on a total weight of the curable composition, at least 25 wt % acrylate monomers based on the total weight of the curable composition, a photoinitiator, and a photosensitizer. The acrylate monomers have a molecular weight of 500 or less. The curable composition has a viscosity of 10 cP or less. A total amount of the expanding monomers and the acrylate monomers are at least 90 wt % based on the total weight of the curable composition.
