FIELD: chemistry.
SUBSTANCE: present invention relates to a protective polyethylene terephthalate film obtained from a polymer synthesized by polycondensation of bis(2-hydroxyethyl) terephthalate, characterized in that during synthesis, particles of carbon nanotubes and organomodified halloysite dispersed in ethylene glycol are included in the polymer, and tetrabutoxytitanium is used as a catalyst, wherein organomodified halloysite is halloysite Al4[Si4O10][OH]8×4H2O, with a specific surface area of 35-70 m2/g, a tube diameter of 5-20 nm, length of 100-150 nm, modified with guanidine acrylate in amount of 10% of the weight of halloysite, where modification is carried out at room temperature by mixing guanidine acrylate with halloysite in an ultrasonic bath for 120 minutes.
EFFECT: providing improved resistance to mechanical action and protection from ultraviolet rays using a polyethylene terephthalate film, the volume of which contains modified halloysite and carbon nanosized filler.
