Acesso em: 14 jun. 2012.00092614http://www.repositorio.ufop.br/handle/123456789/838Molecular mechanics and molecular dynamics simulations were applied in order to study the behaviour of poly ethylene. oxide PEO in different temperatures and solvents. It was found that over the temperature range of 50–500 K the equilibrium structure of PEO is folded. Both kinetic and potential energies increase with temperature. The behaviour of PEO . in two different solvents – CHCl « s5 and H O « s80 – was found to be similar, with the folded structure observed 32 in equilibrium. The solvation energy calculated using the GBrSA model yielded essentially the same value in CHCl and H2O.en-USArtigo publicado em periodicoO Periódico Chemical Physics Letters concede permissão para depósito do artigo no Repositório Institucional da UFOP.
