Summary

A solventless method for preparation of leather-like poromeric resins from various urethane prepolymers is described. The properties of microporous films and coatings on a fibrbus base are found to be dependent on the type and molar ratio of initial polyglycols and diisocyanates. Home-made reagents, catalysts and pore stabilizers can be applied. The properties of leather-like materials of different structure of surface layer are compared with natural leather, Polcorfam and other leather-like materials.
