Abstract
Disclosed herein is a dental material containing a polymerizable hydrolysis stable polycyclic amide monomer. The present disclosure relates to methods of making and use of the polymerizable hydrolysis stable polycyclic amide monomer for the preparation of a dental polymerizable hydrolysis stable polycyclic amide monomer composition. The present disclosure further relates to a cured dental material obtained by polymerizing the dental material.
Claims13
A dental material comprising:
- (i) a polymerizable hydrolysis stable polycyclic amide monomer comprising a compound of Formula (I)
- wherein
- R1, R2, R3 and R4 are independent from each other, and represent a hydrogen, a C1-4 alkyl group or a C5-C18 aryl group;
- R5 is a hydrogen atom, a C1-6 alkyl group, a C3-10 cycloalkyl group, a C7-C12 aralkyl group;
- wherein each group of R5 is optionally substituted by one or more of a C1-4 alkyl group, a C1-4 alkoxy group, or a hydroxyl group;
- R6 is a hydrogen atom, a C1-6 alkyl group, a C3-10 cycloalkyl group, a C1-C12 aralkyl group, a C6-C10 aryl group, an ester or an amide group,
- X is an alkylene group, O, S, or CO;
- n is an integer of from 0 to 1;
- m is an integer of from 1 to 6;
- and
- Z is an m valent unsubstituted or substituted C1-C18 alkylene group, an unsubstituted or substituted C3-C8 cycloalkylene group, an unsubstituted or substituted aralkylene group, an unsubstituted or substituted C5-C18 arylene group or an unsubstituted or substituted C3-C18 heteroarylene group;
- wherein each unsubstituted or substituted group of Z optionally includes at least one of 1-6 oxygen, silicon, sulfur atoms, or NR9, wherein R9 represents a hydrogen atom, straight or branched or cyclic C1-6 alkyl groups;
- (ii) at least one polymerizable resin monomer having at least one (meth) acrylate group, (meth) acrylamide group, allyl group or vinyl group;
- (iii) optionally a particulate filler;
- and
- (iv) at least one of a photoinitiator and a redox initiator.
