FIELD: chemistry. ^ SUBSTANCE: present invention relates to modified diene polymers. The invention describes modified polymers based on conjugated dienes of formula (I): [BR]n-PUR, in which BR denotes a diene polymer, PUR denotes a polyurethyane base, and n is a number greater than or equal to 2. Described also is a method of producing said modified polymers, where compounds containing conjugated dienes are polymerised first, the formed polymers react with polyfunctional isocyanate and/or thioisocyanate compounds, characterised by that the polymer solution obtained from reaction of these polymers with polyfunctional isocyanate and/or thioisocyanate compounds reacts with polyfunctional compounds containing an acidic hydrogen atom. Described also is use of said modified polymers to make tyres and tyre components, for making high-impact polystyrene, copolymers based on acrylonitrile, butadiene and styrene and for making golf balls. ^ EFFECT: obtaining modified diene polymers which are suitable for introduction into rubber mixtures and which improve mechanical and dynamic properties of moulded articles. ^ 10 cl, 4 tbl, 26 ex |
