| Abstract: | The polyurethane elastomers with 0￣60 shore A hardness were synthesized by one step method. The elastomers have a very good resistance to solvents and can be used in printing industry, such as color coating, etc. The influence of isocyanate type, index, polyester structure, curing temperature, etc. on hardness, mechanical properties, solvent resistance of the elastomers was investigated. |
