本研究的目的是比较包含不同光引发系统的五种实验粘合剂混合物的固化反应。测试的假设是树脂共混物的转化度 (DC) 受树脂类型、溶剂含量和光引发系统的影响。实验甲基丙烯酸酯树脂共混物按从疏水性（R2）到亲水性（R3 和 R4）的顺序排列，并以纯态或用 10% 或 20% 乙醇、或 10% 乙醇和 10% 水溶剂化的方式进行测试。使用三种不同的光引发剂：IS-1 = 0.25% CQ（樟脑醌）+ 1% EDMAB（4-二甲基氨基苯甲酸乙酯）； IS-2 = 1.25% TPO（二苯基（2,4,6-三甲基苯甲酰基）-氧化膦）； IS-3 = 0.25% CQ + 0.50% EDMAB + 0.50% TPO。使用差示扫描量热计测量树脂共混物的DC。使用三向方差分析对数据进行分析。纯树脂类型影响 DC，因为与 R2 和 R3 相比，R4 显示出最高值 (p<0.05)。溶剂对 DC 有显着影响（p<0.05）：用 10% 或 20% 乙醇或 10% 乙醇 + 10% 水稀释树脂共混物会增加除 R4 之外的所有树脂的 DC。引发剂影响聚合反应，因为纯树脂和用 10% 或 20% 乙醇溶剂化的混合物在与 IS-1 或 IS-3 聚合时显示出最高的 DC 值 (p>0.05)，而 IS-2 或 IS-3 则增加了用 10% 乙醇和 10% 水稀释的树脂的 DC 值 (p<0.05)。亲水性溶剂化粘合剂配方中应包含与水相容的光引发剂（例如 TPO），以确保粘合剂层具有适当的 DC。
The aim of this study was to compare the curing reaction of five experimental adhesive blends containing different photo-initiating systems. The hypothesis tested was that degree of conversion (DC) of resin blends is affected by resin type, solvent content and photo-initiating system. The experimental methacrylate resin blends were ranked from hydrophobic (R2) to hydrophilic (R3 and R4) and tested as neat, or solvated with 10% or 20% ethanol, or 10% ethanol and 10% water. Three different photo-initiators were used: IS-1 = 0.25% CQ (camphorquinone) + 1% EDMAB (ethyl 4-dimethylaminobenzoate); IS-2 = 1.25% TPO (diphenyl(2,4,6-trimethylbenzoyl)-phosphine oxide); IS-3 = 0.25% CQ + 0.50% EDMAB + 0.50% TPO. DC of resin blends was measured with a differential scanning calorimeter. Data were analyzed with a three-way ANOVA. Neat resin type influenced DC, as R4 showed the highest values compared to R2 and R3 (p<0.05). Solvent had a significant effect on DC (p<0.05): dilution of resin blends with 10% or 20% ethanol or 10% ethanol + 10% water increased the DC of all resins, except for R4. Initiators influenced the polymerization since neat resins and mixtures solvated with 10 or 20% ethanol showed their highest DC values when polymerized with IS-1 or IS-3 (p>0.05), while IS-2 or IS-3 increased the DC values of resins diluted with 10% ethanol and 10% water (p<0.05). Water-compatible photo-initiators such as TPO should be included in the hydrophilic solvated adhesive formulation to ensure an appropriate DC of the adhesive layer.
