The theoretical analysis of relationship of the chemical structure for polymeric networks on the modulus of elasticity fitting within the broad range from 3 to 2000 MPa has been produced. These networks contain bulky cross-linked points, connected by short flexible chains of controlled length. In this paper we prepared the networks derived from polyurethane-iso-cyan urates as well as a combination of polyurethane-iso-cyan urate and polyurethane. The materials possess elastic properties and high wear resistance due to polyurethane component. The polyurethane-iso-cyan urates and polyurethanes of various chemical structures were used for preparation of gradient-modulus materials with the elasticity modulus controlled in the broad range within the same sample or material. The gradient identified as a change in the concentration of monomers per unit distance in a specified direction. This involves creation of molecular gradient regarding the chemical structure of the sample. |
