摘要：

The thermal behaviour of methyl methacrylate polymers functionalized by phosphorus-containing molecules was investigated by TGA/FT-IR and Py-GC-MS under air and argon atmosphere. Three homopolymers and four copolymers with methyl methacrylate (MMA) were prepared and studied. The gases emitted during the degradation of these materials were unambiguously identified, allowing us to suggest a degradation mechanism very different to that of PMMA. The measurement of the LOI values show that the polymers have potential flame retardant properties. (C) 2003 Elsevier Ltd. All rights reserved.
