Abstract

We present both lattice and off-lattice Monte Carlo simulations for multiblock copolymer chains of two lengths, N = 64 and N=128, with microarchitectures (8-8)4 and (16-16) 4 , respectively. The simulations demonstrate that a variety of lattice and off-lattice Monte Carlo methods gives the same protein-like behavior, showing that the multiblock chains undergo a two-step transition, first from a swollen state to a secondary "pearl-necklace" state, and then to a tertiary super-globular state as the solvent quality decreases, that is upon cooling.
