The copolymerization of 3,4-O-cyclohexylidene-D-mannitol 1,2 : 5,6-bis-O-[(4-vinylphenyl)-boronate] (M1) with different N-substituted maleimides and with maleic anhydride has been studied. These monomers copolymerize in 1 : 1 proportion, yielding after removal of the template (3,4-O-cyclohexylidene-D-mannitol) copolymers with bis(4-vinylphenylboronic acid) diads alternating with the other comonomeric unit. By deboronation these diads can be transformed to distyryl diads. These diads possess predominantly (S,S)-configuration; thus optically active polymers with main-chain chirality were produced. The chiroptical properties (optical rotation circular dichroism) of the copolymers were studied. Corresponding copolymers with maleic pride units can easily be transformed by polymer analogous reaction with nucleophiles, as exemplified by alcoholysis with fatty alcohols.
