However, neither TMPEDMA nor any other material increasing resistance to esterases has been commonly applied in dental adhesives, so the release of monomers from them should be taken into account. Toxicity of a chemical compound interacting with living cells may depend on its degradation and/or ...
1.2P(HEMA2co2MMA)水凝胶合成按一定比例配制HEMA与MMA的混合溶液并加入适量交联剂EDMA和引发剂BPO。经磁力搅拌均匀后移入氮气保护箱中,加入定量促进剂DMA(mBPO/mDMA=1/1)搅拌并通氮10min,然后倒入自制聚四氟乙烯矩形模具(13mm×9mm×2mm)中密封,先于20℃下反应固化8h,后于80℃下熟化3h。取出片状聚合物,放入...
