Özet

The effects of varying nitrocellulose concentrations on mechanical properties of polymeric films prepared from UV-curable acrylated urethane prepolymer were investigated. The acrylated urethane prepolymer was synthesized from isophorone diisocyanate (IPDI) and poly(propylene glycol monomethacrylate) (PPGMMA). Isobornyl acrylate (IBoA) and N-vinyl pyrrolidinone (NVP) were used as reactive diluents with the purpose of reducing the viscosity of the prepolymer as well as acting as solvent for nitrocellulose. An increase in nitrocellulose content caused an increase both in tensile strength and elongation values of polymeric films.
