FIELD: chemistry.

SUBSTANCE: invention relates to agriculture. Material, having insecticidal and acaricidal properties, contains: A) 99.95-70.0 wt % propylene-based polymer. The material can be obtained using a catalyst system containing a metallocene compound. The material has the following properties: i) melt flow rate (MFR) (ISO 1133) ranging from 2 to 100; (ii) molecular weight distribution Mw/Mn of less than 4; (iii) stereoregular pentads (mmmm) from 90% to 99%. The material also contains B) 0.05-30 wt % adduct of formula T¹-T². The adduct is obtained from condensation of T¹ and T², where T¹ contains at least one pyrethroid compound. The pyrethroid compound is stable at temperature of at least 150°C. T² is an ethylenically unsaturated compound selected from a group consisting of: (a) a surfactant; (b) vinyl phosphates; and (c) mixtures thereof. Components A) and B) are mixed, heated and extruded. Sheets, films, threads, fibres and a mosquito net are obtained from this material. Nonwoven materials are obtained from threads or fibres.

EFFECT: invention increases efficiency of the material.
