Effect of Short Chain Branching on the Interlamellar Structure of Semicrystalline Polyethylene [PDF]

, 2016
We use molecular simulations with a united atom force field to examine the effect of short chain branching (SCB) on the noncrystalline, interlamellar structure typical of linear low density polyethylene (LLDPE).
