Molecular Simulation Strategies for Understanding the Degradation Mechanisms of Acrylic Polymers
Article describes how acrylic polymers, commonly used in paints, can degrade over time by several different chemical and physical mechanisms, depending on structure and exposure conditions. In this work, the authors studied the effects of different degradation mechanisms and agents on properties of acrylic polymers found in artists’ acrylic paints for the first time using atomistic molecular dynamics simulations.
