ABSTRACT Stable boron resins of high selective absorbent power and their production process. Said boron resins consist of a polyacrylic matrix functionalised with quaternary ammonium groups, an epoxy group and phenylboric groups in accprdamce with general formula (I): Image (I) in which P, R, R1, R2, R3, Y and X are as defined in the text. The resin is prepared by condensing an acrylic resin with an epihalohydrin and then with a halide or hydroxide of an o?iphenyl-aminophenyl- or thiophenyl-boroxin or their alkyl derivatives. Compared with similar currently known resins, the resins of formula (I) have improved selectivity in sugar separation. They can be used for purifying lactulose.
