FIELD: chemistry.
SUBSTANCE: invention relates to a process for the modification of polymers without the use of peroxide or sulfur. Method for modifying a polymer in the presence of elemental sulfur in an amount of not more than 0.5 parts by weight. includes the stages: mixing said polymer with a maleimide-functionalized monoazide in a temperature range of 80–250 °C to form a functionalized polymer and heat treatment of the functionalized polymer in the temperature range 150–270 °C.
EFFECT: invention avoids the isolation of organic volatile substances and fading on the surface of the article.
