The reactive AAEM-modified PMMA adhesive with improved heat resistance

The effect of trimethylol propane triacrylate; TMPTA and glycidyl methacrylate acrylic acid; GMAA as network crosslinking agents were investigated on the thermal stability of the poly(Methyl Methacrylate); PMMA based adhesive. According to TGA analysis, the addition of 0.5 phr of GMA resulted in more pronounced heat resistance than TMPTA in acetoacetoxy ethyl methacrylate; AAEM modified MMA adhesive. The results of the adhesive lap joints after 24 hours exposure at 150 ºC showed almost an increasing thermal stability for GMA counterpart. The improved thermal stability was mainly attributed to the presence of the glycidyl ring and its incorporation into network crosslinking.
