In order to prepare special alcohol-soluble polyvinyl butyral (PVB), the reaction condition was explored in this paper after analyzing the molecular structure of PVB. Under a simple and economical condition, PVB with 14.2% of butyraldehyde group and good alcohol-solubility were prepared, the PVB film forms quickly after the volatilization of ethyl alcohol, and it has good diaphaneity, high tensile strength, and excellent mechanical properties. The highest tensile strength of the PVB film reaches 50.9MPa, which can meet some requirements of many applications. |
