Gradient polymeric materials

Data on gradient polymeric materials that possess broadly varying mechanical, optical, and other properties are generalized. The term “gradient materials of the first type” refers to materials that possess a gradually variable elasticity modulus in the range of 3–2000 MPa for the same material that possesses no layers or interfaces, pasting, heat sealing, etc. They are produced as either transparent molds or composites with various reinforced fillers. The synthesis of these materials is based on the formation of polymer networks containing bulky cross-linked points with short flexible fragments linking them. These networks have been computer simulated using the physical approach developed by the authors and the chosen software, which allows one to calculate polymer properties based on their chemical structure and the implementation of computerized synthesis of polymers with prescribed properties. The term “gradient materials of the second type” refers to materials with abruptly changing elasticity modulus and transition zone between the glassy and the rubbery states.
