Beschreibung
Zusammenfassung:	The invention discloses a preparation method capable of rapidly dissolving a PVA resin. The method is characterized by comprising the following steps: by taking vinyl acetate and acrylic acid as raw materials and taking tert-butyl peroxypivalate as an initiator, thereby obtaining a copolymer solution; and adding a NaOH methanol solution into the copolymer solution, performing alcoholysis, thereby obtaining the PVA resin which can be rapidly dissolved. The PVA prepared by the method disclosed by the invention can be completely dissolved under the condition of 85 DEG C, and the dissolution time is 3-5 hours.
