Abstract: With butyl cyanoacetate and paraformaldehyde as main raw materials,a α-cyano butyl acrylatemonomer was synthesized by polycondensation and cleavage reaction,and the α-cyano butyl acrylate medicaladhesive was prepared. The influences of plasticizer,curing catalyst(polyethylene glycol dimethyl ether)onflexibility,curing speed and bonding force of medical adhesive were emphatically discussed,and the biologicalproperties of medical adhesive were characterized. The research results showed that the adhesive could fully meetthe medical requirements because it had the relatively best toughening effect and the relatively larger curing speed,and it had no hemolytic reaction and allergic reactions when mass fractions of plasticizer and curing catalyst were10% and 1.5% respectively in total mixture.
