ABSTRACT Chitinase-catalyzed copolymerization of an _N_,_N_′-diacetylchitobiose oxazoline monomer (1) with an _N_-acetylchitobiose oxazoline monomer (2) has been investigated. Catalysis of

chitinase derived from _Bacillus_ sp. showed close polymerizability of these two comonomers, giving rise to the corresponding copolymer. The degree of _N_-deacetylation (DDAc) of the product

was controlled by varying the comonomer feed ratio. In contrast, catalysis of chitinase from _Serratia marcescens_ showed different reactivity of the comonomers. Thus, homopolymerization of

monomer 2 was preferentially occurred at the beginning of the reaction and copolymer was hardly obtained. SIMILAR CONTENT BEING VIEWED BY OTHERS BIOTECHNOLOGICALLY PRODUCED CHITOSANS WITH
