A mechanism for the cross-linking reaction between two PVA molecules and formaldehyde in an acidic condition is to be proposed. Concept introduction: In cross-linking reaction, one polymer chain links with another polymer chain. The hydroxyl groups of two PVA molecules link through formaldehyde in an acidic condition. As the reaction occurs in acidic condition, it proceeds with protonation of formaldehyde oxygen, converting it to more electrophilic.
