Responsive and Dynamic Cross Linking Polymeric Binder/Liner Systems

Abstract

The effect of glass transition temperature on the thermal decrosslinking of Diels-Alder crosslinked poly(n-alkyl methacrylate) networks was studied. A series of networks possessing a range of glass transition temperatures was prepared by copolymerizing two n-alkyl methacrylic monomers at various feed ratios, and the influence of the Diels-Alder crosslinker was evaluated by comparison against triethylene glycol dimethacrylate-crosslinked thermosets and uncrosslinked thermoplastics using dynamic mechanical analysis. Preliminary examination of other DMA signals such as loss modulus and particularly tan delta suggests some degree of retro Diels-Alder reaction is occurring, and current efforts to correlate the aforementioned mechanical property data with calorimetric data are underway.
