Scrutiny of viscoelastic behavior of Chloroprene/Poly(methyl methacrylate) interpenetrating polymer networks

Interpenetrating polymer networks (IPNs) combining chloroprene (CR) and poly(methyl methacrylate) (PMMA) networks were prepared using a sequential strategy. We tried to merge the properties of chloroprene rubber and poly(methyl methacrylate) with IPN technique. The glass transition of chloroprene and poly(methyl methacrylate) occurs in -50 and 105 ˚C, respectively. In glassy state, due to segmental motions of macro molecules, polymers provide best area of their attenuation behavior. With IPN structure this combine achieves to a broad glassy state and subsequently a broad area for damping behavior. In this study, we also have reviewed nano clay and cross-linker (%wt) of methyl methacrylate role in mechanical properties of mentioned IPN
