Abstract

The use of high intensity ultrasound to promote a number of reactions at the surface of solid poly(vinyl chloride) is reported. Substitution reactions involving a range of compounds, including dyes, can rapidly be carried out from aqueous solution under labile conditions. Sonochemically enhanced treatment with strong aqueous base produces dehydrochlorination even at room temperature to produce a thin layer of conjugated material at the surface which can then be grafted with a number of compounds. Some speculation as to the mechanistic features of the process as well as its potential utility is made.
