PROBLEM TO BE SOLVED: To provide a method for producing a dental adhesive capable of reduce inconveniences of inhibiting osteogenesis which may happen in the time of using a conventional dental adhesive.SOLUTION: A dental adhesive is obtained by ester-copolymerization of 3,4-dihydroxycinnamic acid and 3-(3-hydroxyphenyl) propionic acid using acetic anhydride and dibasic calcium phosphate as a catalyst. An amount of acetic anhydride and dibasic calcium phosphate used as an esterification catalyst is preferred to be 0.01-10 parts by mass based on 100 parts by mass of a total amount of 3,4-dihydroxycinnamic acid and 3-(3-hydroxyphenyl) propionic acid as a raw material monomer. A reaction temperature is preferably 80-300°C. A reaction time is preferably 12 to 30 hours. |
