| Abstract: | The environment-friendly fructose-hydroquinone resins weresynthezised by reaction of fructose instead of formaldehyde with hydroquinone in alkali condition.The fructose-hydroquinone resin was characterized by the infrared spectrum,TG analysis and GPC.Response surface methodology （RSM） was utilized for optimizing the reaction conditions. The results showed that,when the amount of catalyst was 3.99 wt%,reaction temperature was 69.97%,reaction time was 9.03h and molar ratio of fructose and hydroquinone was 9.29,the optimal viscosity of the resultant product was 222.808 mPas and the bonding strength reached 23.6MPa.The fructose-hydroquinone resins are biodegradable,which have better performance in industrial application. |
