説明
Several polyvinylalcohols having one to two aldehyde group per one molecule (D-PVA) were prepared by cleavage of 1, 2-glycol bonds in polyvinylalcohol with periodic acid. The intermolecular acetal formation was carried out in water under existence of acid catalyst, and the viscosity change of solution with reaction time was measured. After a certain time the solution becomes a gel which is insoluble in boiling water. The time to gel decreases with increase of aldehyde group per one D-PVA molecule at the same condition, and with increase of concentration of D-PVA at the same sample.
