Synthesis of Copolymers of N-Vinylpyrrolidone with Crotonic Acid Modified with 4-Oxybenzaldehyde

Resumo

Radical copolymerization of N-vinylpyrrolidone with crotonic acid in 2-propanol has afforded water-soluble products, which have been characterized in terms of composition as well as molecular and hydrodynamic parameters. The obtained copolymers have been modified with 4-oxybenzaldehyde. Structures of the products of the polymer analogous reaction, potential carriers of several bioactive substances, have been confirmed using elemental and functional analysis and spectroscopic data.
