Thermoplastic resin, hydrolyzed into polyvinyl alcohol in acid or alkaline solvents, is the main raw material for preparing polyvinyl alcohol. When molecules contain photosensitizers, they are sensitive to light and undergo decomposition reactions under the action of ultraviolet light or electron beams, exhibiting positive photosensitive resin properties. It can copolymerize with various monomers with double bonds, introducing various functional groups and possessing different properties.
