Abstract

Multifunctional film materials based on highpressure polyethylene have been developed and manufactured by modifying the polymer matrix with chemically active reagents (insecticides from the classes of synthetic pyrethroids, organophosphorus compounds, neonicatinoids and a UV stabilizer (Tinuvin 783)), optimized for prescription, structural, physical, physical chemical parameters and bioactivity.

Investigations held by the method of IR spectroscopy have shown that there is the formation of an ether bond between the molecules of the components in insecticidal polymer composites.

The kinetic dependence of the release of the liquid phase from the surface of a composite polyethylene film of the composition LDPE/DOP/insecticide/ Tinuvin 783 is presented.

The insecticidal film of prolonged action will solve the problem of protecting agricultural land, conifer and deciduary forest plantations from phytophagous insects, as well as reduce losses from biological damage to light industry products packed in film cases.
