Abstract

The glass transition of a two-dimensional melt of lattice polymers is discussed. The glass temperature Tg is determined by the free volume approach, by the isothermal compressibility as well as by other methods. The decay of the bond autocorrelation function displays typical glasslike behavior. The time temperature superposition law detected in the dynamical polymer structure factor and in orientational autocorrelation functions can be explained by simple dynamical scaling arguments. Mean square displacements observed over more than five decades in time yield very precise diffusion constants as a function of temperature.
