Polymeric compositions for use in preparing a ballistic material and ballistic materials capable of absorbing incoming projectiles prepared from the polymeric material are disclosed The resulting ballistic materials are also disclosed The materials have sufficient elasticity so that the polymer or polymer blend does not shatter when stuck with a high-velocity projectile The polymer blends ideally have one or more of the following physical properties—a) a modulus of elasticity in the range of around 12,500 psi and around 19,000-psi, b) a max stress psi in the range of around 545 and around 985, and c) a tensile strength in the range of around 3 50 ft-lbflιn and around 11 OO ft-lbf/ιn The thickness of the ballistic material is at least around 3 inches, with a size of around 4-5 inches square or diameter
