| Abstract: | A new type resin VMP-1 used in foundry of vacuum-sealed moulding process is piesented. It is a rapid filming material at room temperature and consists of copolymers of both vinyl acetate(VAc) and methyl methacrylate (MMA) including mixed polymers of pyAc and PMMA. Its synthesis and the mechanism of film stripping are studied and its infrared spectrum as well as mechanical and thermal properties are in ve stigated. Experimental results show that the new resin is of less toxicity, high tensile strength, high filming speed and good performance. |
