    • Processes are described for preparing polyurethane polymers by reacting an isocyanate with an alcohol using a non-tin based catalyst having the formula where R1, which are identical or different, are a fluoroalkyl, monovalent alkyl, cycloalkyl, (cycloalkyl)alkyl, or the ring of the cycloalkyl group that optionally comprises at least one heteroatom, R2 represents a hydrogen atom, an aromatic, arylalkyl, fluoroalkyl, alkylamine, alkylguanidine, monovalent alkyl, cycloalkyl or an alkyl group substituted by an optionally substituted ring, which optionally comprises at least one heteroatom, and R3 represents an arylalkyl, fluoroalkyl, alkylamine, alkylguanidine, monovalent alkyl, cylcoalkyl, or alkyl group substituted by an optionally substituted ring which optionally comprises at least one heteroatom, when the R2 radical is not a hydrogen atom, the R2 and R3 radicals optionally being linked to form a 3 to 7 membered optionally substituted aliphatic ring, and the R1, R2 and R3 radicals do not comprise a silicon atom.
