abstract

• A relationship between chain graft density calculated by coarse-grained simulation and the one obtained from experimental results is compared in the present work. Two slip additives for polypropylene films were studied, erucamide and stearyl erucamide. The diffusion equation (Fick%27s second law) was used to relate real-time experimental results with coarse-grained simulations and rendered slip additive surface density as a function of the coefficient of friction. The normalized surface density values obtained from the simulation showed a qualitative trend consistent with the experimentally observed results. © 2021 Society of Plastics Engineers.
