FIELD: chemistry.
SUBSTANCE: invention refers to the modification of polymers, particularly oxidised polyfluoralkylation of oxidised polypropylene, which can be used in manufacturing wire cable, pipe laying on the bottom. What is described is a method for the hydrophobisation of oxidised isotactic polypropylene. The method is based on modification by introducing fluorine-containing fragments into structural elements of a polymer chain by means of a fluorinated agent in a solvent medium. Thereafter, the modified polymer is isolated and dried. Suspended oxidised isotactic polypropylene is modified with the use of octafluoropentylchlorosulphite in the presence of a catalyst dimethyl formamide in the chloroform medium.
EFFECT: producing the polymer material with improved hydrophobic properties.
