Photopolymerizable compositions featuring novel amine accelerator for improved color stability and reduced polymerization stress thereby |
摘要 |
A photopolymerization accelerator composition improving color stability and controlling polymerization shrinkage stress of cured resin and/or the resulting composite paste thereby feature by tertiary twisted biphenyldiamine with the general formula I:;
R2 and R3 are each independently alkyl having from 1 to 5 carbon atoms; R and R1 are each independently hydrogen or halogen; alkyl alkoxy, or alkylthio having from 1 to 18 carbon atoms; or phenyl and/or substituted phenyl alkoxy, or alkylthio having from 1 to 18 carbon atoms. It can be used in part with conventional photosensitizers and radically polymerizable monomers. |

1. A photopolymerizable composition comprising an aromatic tertiary diamine having a twisted biphenyl moiety, a photosensitizer, and at least one polymerizable resin;
wherein the at least one polymerizable resin consists of at least one of a monofunctional (meth)acrylate monomer or a polyfunctional (meth)acrylate monomer; and wherein the aromatic tertiary diamine having the twisted biphenyl moiety is selected from the group consisting of: and combinations thereof. |
