The relaxation in a simple bead-spring polymer system in the supercooled regime near its glass transition temperature was investigated with Molecular Dynamics simulations. The relationship between the structural and dynamic behaviour experienced by the glass former when it approaches the glass transition temperature (Tg), is key to understanding the formation of glasses.1 In this work, we introduce a new approach to look at the dynamic lengthscales that emerge in linear polymer, focusing on the tendency of the monomers to be dynamical correlated, through a Isoconfigurational Ensamble (ICE) Method.
