Capturing agent tolans, the anti-oxidant core of traditional binary antioxidant series are to capture using hindered phenol anti-oxidants
Peroxy radical or effective hydroperoxide decomposition, tolans of the invention can polypropylene extrusion process
In, carbon radicals are captured, carbon radicals is on the one hand inhibited to cause thermo-oxidative ageing degradation, on the other hand reduce carbon certainly
It is further aoxidized by base and generates peroxylradicals so that polypropylene is in oxidation process at the very start to polyacrylic oxidation
Reaction is limited, and the pressure for then capturing peroxy radical is reduced, and significantly reduces double octane amine and phosphite ester mistake
The dosage of oxide radical, and improve the colour stability of woven bag.
