FIELD: chemistry. ^ SUBSTANCE: described is a norbornene and acrylate copolymer of structural formula: where R=Me, Bu1, n and m are indices which determine composition of copolymers, n=12-75 mol %, m=100-n mol %, having weight-average molecular weight Mw from 450000 to 1400000 (g/mol) and polydispersity index Mw/Mn from 1.5-2.4, obtained through a radical copolymerisation reaction in the presence of a radical initiator using methyl acrylate or tert-butyl acrylate as a comonomer, with ratio norbornene: comonomer from 3:1 to 1:1 mol/mol. Described is a method of producing said norbornene and acrylate copolymer via radical copolymerisation, characterised by that copolymerisation is carried out at temperature 25-30C in the presence of a radical initiator, and the comonomer used is methyl acrylate or tert-butyl acrylate with ratio norbornene: comonomer from 3:1 to 1:1 mol/mol. Described is a method of producing a nanocomposite by mixing a polymer matrix and a semiconductor, characterised by that the polymer matrix used is a norbornene and acrylate copolymer in claim 1, and the semiconductor used is cadmium selenide nanoparticles with particle size from 2.2 to 3.3 nm in amount of 1 to 10 wt % with respect to the polymer matrix. ^ EFFECT: obtaining copolymers having an improved system of physical and chemical properties: high transparency, film-forming, mechanical and adhesion properties. ^ 4 cl, 2 tbl, 10 dwg, 16 ex |
