초록
Bis-GMA is an important component in commercial dental restorative composites, but its hydroxy groups are considered to promote water absorption of the cured composite in a mouth. In this work, multifunctional methacrylates were prepared by blocking the hydroxy groups in bis-GMA with methacryloyl groups. Comparing to bis-GMA, new prepolymers having three methacryloyl groups (BPA-3M) and four methacryloyl groups (BPA-4M) showed much lower viscosities. Photopolymerization conversion of BPA-3M was slightly higher than that of bis-GMA. Water absorption of the photo-cured composite containing BPA-3M was measured for one month and found to be much lower than that of bis-GMA.
