The preparation of cyclohexanone-formaldehyde resins containing functional
groups such as carboxylic acid, eater, phenol and vinyl is described. These
resins were obtained by in situ modification of a cyclohexanone-formaldehy
de resin. Modifier compounds were 1,4-cyclohexanedione, salicylic acid, o-c
resol, p-cresol, citric acid, glyoxal, benzaldehyde, acetaldehyde, and acry
lamide. Conductivities of the resin modified with glyoxal and acetaldehyde
were 10(-4) and 3 . 10(-3) S cm(-1), respectively.
