Thermal and Rheological Properties of Polymethyl Methacrylate Plasticized with New Resinous Plasticizers

摘要

Polymethyl methacrylate (PMMA) is one of the important commercial glassy polymers, but unfortunately it undergoes depolymerization when subjected to elevated temperatures, i.e., above 190#xB0;C. Thus, thermoforming by the usual technological process is accompanied by severe difficulties, and therefore the development of some convenient processing plasticizers might be of great importance.
