✦ Synopsis

Abstract

Poly(vinyl alcohol) (PVAL) samples partially functionalized with 4‐nitrophenyl carbonate groups were obtained by reaction of PVAL with 4‐nitrophenyl chloroformate using pyridine as a catalyst. 2‐Amino‐2‐deoxy‐D‐glucose (glucosamine) was virtually quantitatively bound to PVAL activated with 4‐nitrophenyl carbonate groups. Glucosamine‐carrying PVAL (PVAL‐G) and Concanavalin A (Con A) in phosphate buffer (pH 7,2) at room temperature were proven to interact with each other.
