Abstract	The static mechanical (uniaxial compression at a low strain rate \(\dot \varepsilon \) ≤ 10−4 s−1) and thermomechanical properties of triethylene glycol dimethacrylate (M1) copolymers with vinyl monomers (M2) were studied and analyzed by means of a program developed earlier for identification of structural and physical features of macromolecular networks. The copolymer composition for each monomer pair was varied over the entire range of 0–100 mol % with a step size of 25 mol %. As M2, monomers that ensure different types of unit distribution in chains were selected: alkyl methacrylates (random distribution), styrene (unit alternation tendency), butyl acrylate (block formation tendency), and vinyl acetate (tendency to form chains that are enriched initially in M1 and finally, as M1 is consumed, in M2). To reveal the possible shielding effect capable of lowering the likelihood of the side process of intrachain crosslinking (cyclization), alkyl methacrylates with different degrees of bulkiness of the alkyl radical—methyl, butyl, and lauryl—were used. A systematic study of this representative set of test compounds showed that copolymerization imparted unusual and a priori unpredictable properties to the copolymers formed.
