The Synthesis of Oligomeric Derivatives of Gossypol and the Study of their Antioxidative Properties
Abstract
A study was made of the synthesis of oligomeric derivatives of gossypol with epichlorohydrin and allyl halides. The structure of the oligomeric derivatives of gossypol was confirmed by IR spectroscopic and elemental analysis. The antioxidative capacity of the oligomeric derivatives of gossypol in the inhibition of low-density polyethylene (LDPE) was investigated. Study of the antioxidative properties of the synthesised oligomeric antioxidants by mass chromatography showed that comparison of the decomposition products of LDPE made it possible to conclude that the antioxidants affect the process of C–C bond rupture. The number of R–In bonds formed during the degradation of LDPE can serve as the main criterion of stability of stabilised specimens
