| Abstract: | The novel photosensitive prepolymers were synthesized by the block copolycondensation of unsa-turated polyester with epoxy resin. There are two steps in the synthetic procedure of photosensitive prepolymers. The first step is to prepare the unsaturated polyesters having a certain molecular weight terminated by carboxyl. The second step is to prepare prepolymers by the block copolycondensation of above polyesters with epoxy resin. The molecular weight of prepolymer can be controlled by adjusting the molecular weight of unsaturated polyesters. Based on above photosensitive prepolymers, some recipes of photosensitive coating were present in this paper. The photo-curing kinetics and properties of coating films such as surface hardness, flexibility and adhesion were determined. |
