The invention relates to a vibration-absorbing polymer material and a method of its producing. The vibration-absorbing polymer material is a reaction product of toluene diisocyanate and polyoxypropylene taken at their stoichiometric molar ratio of 2:1 respectively, and obtained by solidification at 50- of a reaction mixture, while mixing toluene diisocyanate and polyoxypropylene is carried out at 45-, preparation of the reaction mixture is carried out by introducing trimethylolpropane in the product of reaction of toluene diisocyanate and polyoxypropylene glycol heated to the temperature of 60-. The produced vibration-absorbing polymer material has high damping properties in the temperature range from 5 to and wide frequency range, and can also be used to produce parts of complex configuration. |
