文摘

A synergism between methyl methacrylate and an amphiphilic ionic liquid acrylate 1-(11-acryloyloxyundecyl)-3-methyl imidazolium bromide (IL) not only increases the apparent thermal stability (kinetic retardation of thermal decomposition) of poly(MMA-co-IL) copolymers by 50 掳C at relatively low doping levels of 0.5 mol %, but also increases the storage (10%) and loss (15鈥?5%) moduli over 0鈥?5 掳C (increasing the elasticity). Moderate to high doping levels provide plasticization without the risk of leaching or plasticizer contamination.
