摘要 2'-methacryloxy-3α,7α12α-trimethacryloylcholicacidethylester(CAGE4MA)hasbeenpreparedfromcholicacid.Photo-polymericresinswerepreparedfromCAGE4MA.2,2-bis[4-(2-hydroxy-3-methacrylyloxypropoxy)phenyl]propane(bis-GMA)wasusedforcomparison,triethyleneglycoldimethacrylate(TEGDMA)wasusedasdiluent.Thepolymerizationwasinitiatedbycamphoroquinone(CQ)/N,N-dimethylaminoethylmethacrylate(DMAEMA)system.TheconversionofCAGE4MAwas39%whenthereactiontimeis60s,whichislowerthanbis-GMAandTEGDMA.TheswellingvalueofCAGE4MAresinwas0.41%indistilledwater,whichismuchlowerthanthoseofbis-GMAresin(2.04%)andTEGDMAresin(4.77%)underthesameconditions.CopolymersfromCAGE4MAandTEGDMAhavebeenprepared.WiththeincreaseofTEGDMAinmixture,thedegreeofconversionofCAGE4MAandswellingvalueincreased.Theswellingvaluesofphotocuredresinsin0.1mol/LHClwerealsomeasured.
