Resumen:
The use of effective initiators is the key for a successful synthesis of complex macromolecular architectures by anionic polymerization techniques. In this work we report the synthesis and polymerization performance of a soluble initiator obtained by the reaction of naphthalene (Naph) and lithium metal (Li), under mild experimental conditions. Its efficiency was tested in homopolymerization reactions by using different monomers such as styrene (S), isoprene (I) and hexamethyl(cyclotrisiloxane) (D3). Lithium naphthalenide initiators were synthesized under mild conditions by employing different [Li:Naph] ratios, room temperature, and benzene or benzene/THF mixture as solvent. Model homopolymers such as PS, PI, or PDMS were obtained with these initiators, which clearly show the suitability of the experimental procedure employed.
