Abstract: Four kinds of alkyl vinyl sulfoxides were synthesized.The Michael addition reaction of vinyl sulfoxide with poly(vinyl alcohol) in the presence of NaOH as catalyst has been studied in detail.Polymers with various sulfoxide contents were prepared and characterized by means of 1H NMRand IR spectra.

Key words: Vinyl sulfoxide, Poly(vinyl alcohol), Michael addition reaction, Characterization
