The inhibition effects of five 1-isonicotinoyl-4-arylthiosemicarbazides and some 1,2,4-triazoline-5-thione derivatives on the polymerization of VAc, initiated by AIBN, have been investigated by dilatometric method. The results showed that being added in the amount of 1000-3000ppm, the thiosemicarbazides have a more prominent inhibiting effect than trizoline-5-thiones. When the compounds studied were incorporated with 1,4-benzoquinone or hydroquinone the inhibiting effect increased strikingly.
