Two multimethacrylates having three methacrylate groups (BPA-3M) and four methacrylate groups (BPA-4M) have been prepared by reacting hydroxyl groups of 2,2-bis[4-(2Ј-hydroxy-3Ј-methacryloyloxypropoxy)phenyl]propane (Bis-GMA) with methacryloyl chloride. BPA-3M and BPA-4M have much lower viscosities
Polyurethane polymers are a wide class of materials, ranging from surface coatings and adhesives to flexible or rigid foams. However, polyurethanes in general are very flammable and produce heavy smoke when burning. As a result of their flammability, there is a great interest in the development of m
