NORBORNENE AND ACRYLATE COPOLYMER, SYNTHESIS METHOD THEREOF AND METHOD OF PRODUCING NANOCOMPOSITE BASED THEREON Russian patent published in 2012 - IPC C08F220/10 C08F232/04 B82B1/00 

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 M_w from 450000 to 1400000 (g/mol) and polydispersity index M_w/M_n 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 25-30°C 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.
