OXIDIZED ATACTIC POLYPROPYLENE WITH THE POLAR FUNCTIONAL GROUPS, THE METHOD OF ITS PRODUCTION AND THE INSTALLATION FOR THE METHOD REALIZATION Russian patent published in 2007 - IPC C08F8/06 C08F110/06 B01J8/22 

FIELD: chemical industry; the methods and installations for production of the oxidized atactic polypropylene.

SUBSTANCE: the invention is pertaining to production of the oxidized atactic polypropylene with the molecular mass of 5500-38000 and the polar functional groups, which may be used as the component of the various composite materials, the multipurpose additives for lubricants, anticorrosion coatings. For production the above-indicated oxidized atactic polypropylene they use the industrial atactic polypropylene with the molecular mass of 20000-40000 and the oxidization conduct at least in two stages with the adjustable temperature drop from 250 to 150°С within 1-6 hours at the air consumption of 0.6-1.9 l/(minute·kg). The installation for the method realization contains at least two in series connected reactors supplied with the electric heater at the ratio of the height of the reactor to its diameter laying within the limits of 2.0-5.0, the device for the air supply is made in the form of the vertical pipe with the air supply through its upper part and in the lower part it is supplied with the nozzle with the slits arranged along the perimeter of the lower edge. At that the diameter of the nozzle with respect to the diameter of the reactor is chosen within the limits of 0.25-0.5.

EFFECT: the invention ensures production of the oxidized atactic polypropylene with the molecular mass of 5500-38000 and the polar functional groups, which may be used as the component of the various composite materials, the multipurpose additives for lubricants and the anticorrosion coatings.
