Abstract: Described herein is a dental composition containing a polymerizable compound having at least one optionally derivatized β-hydroxy urethane unit. The polymerizable compound having at least one optionally derivatized β-hydroxy urethane unit is obtained without use of organo-metal catalysts and isocyanates and by a reaction between an at least one component A having at least one cyclic carbonate group with an at least one component B having at least one of primary amine functional group and secondary amine functional group. The present disclosure relates to use of the polymerizable compound having at least one optionally derivatized β-hydroxy urethane unit for the preparation of a dental composition, in particular a dental composite, a glass ionomer, a dental cement, a dental sealant, and a dental adhesive.

Abstract: The present invention is related to a curable dental two-pack composition comprising: (a) a first paste comprising (a-1) one or more crosslinker having at least four primary amino groups; and (b) a second paste comprising (b-1) one or more compounds polymerizable with a crosslinker of the first paste in a step-growth polymerization reaction; wherein (b-1) the compound polymerizable with the crosslinker compounds is a compound of the following formula (II): wherein A is a hydrocarbon group which may contain one or more hetero atoms selected from oxygen and sulfur atoms; R1 is as defined in claim 1; R4, R5, R6 and R7 are independent from each other and represent a hydrogen atom or a methyl group and the Y, which are independent from each other represent a single bond, an oxygen atom, a sulfur atom, an ester bond or a urethane bond.
