Abstract
Summary: Acrylic acid was polymerized and modified with some acids such as salicylic acid, benzalthiobarbituric acid and some amines such as aniline and a-naphthylamine. Modified polyacrylic acids (PA) were characterized with FT-IR spectroscopy and thermal analysis and their ability was tested to be antioxidants for PVC which contains sensitive terminal double bonds toward oxidative conditions. The extent of PVC discoloration is considered to follow up the degrading thermal oxidation. All the investigated polyacrylic acid derivatives showed ability as polymeric antioxidants better than the unmodified especially polyacrylylbenzalthiobarbituric acid. The results obtained are justified and discussed.
