【摘要】 <正> α-氰基丙烯酸酯类粘合剂具有流动性好、室温快速固化、单组份(不需要外加催化剂)、使用方便、生物适应性好等优点。但由于热稳定性和水老化性能较差,而大大限制了使用范围。特别是应用到口腔内,它的水老化性能应当是重要指标之一。近年国内外在改进氰基丙烯酸酯类粘合剂性能方面采用了在其单体更多还原

【Abstract】 Ethylene glycol bis (2-cyano acrylate)has been synthesized and added to ethyl 2-cyano acrylate and propenyl 2-cyano acrylate adhesives. The addition of the monomer containing two functional groups can evidently increase the water-stability of these adhesives and improve their heat-resistant and solvent-resistant properties.The adhesives modified by ethylene glycol bis (2-cyano acrylate) have been used to bond rubber attachments to teeth for the treatment of mandibular fractures. Clinical observations have been made for two years and the results are satisfactory.更多还原
