Abstract
The flammability of poly (methyl methacrylate) (PMMA) poses a fire safety hazard to its applications. A hybrid of piperazine pyrophosphates (PAPP) and aluminum diethylhypophosphate (ADP) were used to modify the flame retardancy of PMMA, and a phosphorus-containing vitrimer (V) was incorporated to toughen the PMMA blends. The PMMA containing 20 wt% PAPP/ADP achieves the UL-94 V0 rating with an increased limiting oxygen index (LOI) value of 24.3 vol%. After incorporating 2.0 wt% V into flame retardant PMMA, both the UL-94 V0 rating and an increase of 56 % for the impact strength of PMMA blends are obtained. The gas-condensed hybrid effects of ADP/PAPP modify the flame retardancy of PMMA and the transesterification between vitrimer and PMMA enhances its mechanical properties. This provides a feasible method to prepare PMMA blends with good comprehensive performances.
期刊介绍：
Reactive & Functional Polymers provides a forum to disseminate original ideas, concepts and developments in the science and technology of polymers with functional groups, which impart specific chemical reactivity or physical, chemical, structural, biological, and pharmacological functionality. The scope covers organic polymers, acting for instance as reagents, catalysts, templates, ion-exchangers, selective sorbents, chelating or antimicrobial agents, drug carriers, sensors, membranes, and hydrogels. This also includes reactive cross-linkable prepolymers and high-performance thermosetting polymers, natural or degradable polymers, conducting polymers, and porous polymers.
Original research articles must contain thorough molecular and material characterization data on synthesis of the above polymers in combination with their applications. Applications include but are not limited to catalysis, water or effluent treatment, separations and recovery, electronics and information storage, energy conversion, encapsulation, or adhesion.
