The kninetics of acid-catalyzed acetalization and ketalization of poly(viny1 alcohol) (PVA) were systematically studied in completely homogeneous media with carefully selected solvents. Thus the acetalization reaction was run in water with six aldehydes [RICHO (R, = H, CH3, CZH5, n-C3H7, i-C3H7, CIC

A kinetic study was carried out on the acetalization reaction of 1,3-butanediol, as a model compound for poly(vinyl alcohol) (PVA), in water, under acidic conditions. Since these equilibrium constants of ketalization reaction of 1,3-butanediol and ethylene glycol are so small, the kinetic parameters

Ketalization reaction of polyvinylalcohol (PVA) by methyl ethyl ketone (MEK), dimethylsulfoxide (DMSO) as solvent, under the presence of acidic catalyst, in homogeneous system was carried out, and the synthesis of polyvinylketal with any ketalization degree was successfully performed. The reaction m
