The invention is directed at current research situation and existing problems of oxygen absorbents and develops a novel oxygen absorbent with effectively improved compatibility and enhanced oxygen absorption effects. According to the invention, the problem of poor compatibility of organic oxygen absorbents in a polyester material is essentially changed, and 1,3-bivinyl-4,6-phthalic acid and polyester are more compatible; the oxygen absorbent is allowed to undergo graft copolymerization in the polyester material and is uniformly dispersed, and catalytic and oxygen absorbing effects of the obtained oxygen absorbent are more stable and excellent. |
