Poly(vinyl thiol) was synthesized by the acid catalyzed thiolation of poly(vinyl alcohol) with thiourea, followed by the hydrolysis of the corresponding thiouronium salt. The polymer was characterized by a combination of FTIR, NMR and DSC which indicated complete conversion of the OH groups to SH functionalities but only a minor change in the value of the glass transition temperature (77 - 80 °C). Wheat gluten blends with this additive are currently evaluated for improved mechanical and water absorption characteristics.
