Namely, one unimodal type (HDPE-1) and two bimodal type. Structure of PE samples was characterized by 13C NMR (Carbon-13 nuclear magnetic resonance). The Taylor impact test was used. Specimens in form of a cylinder (14 mm in diameter and 50 mm in length) were fired against a steel bar. Striking velocities achieved up to 116 m/s. No permanent strain of these specimens was detected. Numerical simulation of these tests showed that the material behavior is probably viscoelastic. Results showed that there was no difference in the impact behavior of tested polymers. This conclusion was obtained both for the results in the time domain and the frequency domain.
