摘要
Using triethylamine as a catalyst, two polyacrylates containing both acid anhydride and hydroxylic groups were prepared and could be cured with each other under ambient condition to give a coating with good performances. The crosslinking degree of the cured coating amounts to 77% at the catalyst mass fraction higher than 3 6%. With increasing the catalyst mass fraction from 3 6% to 5 4%, the hardness, flexibility and adhesion of the coating were all improved accordingly.
