Abstract
Procedure for obtaining synthetic polyurethane materials with the structural unit **(See formula)** wherein R means a C1-C20 alkyl moiety, optionally branched and/or containing heteroatoms, preferably oxygen or sulfur and R'means a C1-C10 alkyl moiety, characterized in that polyhydroxy compounds of molecular weight comprised between 800 and 5000 with polyisocyanates and aromatic diamines, as chain extension agents, of general formula **(See formula)** wherein R represents a C1-C20 alkyl radical, optionally branched and/or containing heteroatoms, preferably oxygen or sulfur and R'means a C1-C10 alkyl radical.
