FIELD: chemistry.SUBSTANCE: invention relates to a method of modification of a polyetheleneterephalate (PET) film surface by functional additives and can be applied in the production of containers, packing, fibres and tribotechnical products. The method of modification of the polyetheleneterephalate film surface includes processing the surface with a modifier - 1,1,3- trihydroperfluoroepropanol-1 with heating in an ethanol medium, at a temperature of 40°C and frequency of ultrasound 40 kHz for 2 h.EFFECT: invention makes it possible to increase a degree of PET crystallinity, and obtain PET with an improved complex of thermal, mechanic and moisture-resistant properties.2 tbl, 1 ex |
