MARIA Cazacu, ANGELICA Vlad, FELICIA Iacomi, PETRU Budrugeac, AURELIA Ioanid Condensation Products of the Bifunctionalized Titanocene and Siloxane Derivatives


Abstract:
Various telechelic bifunctionalized siloxane derivatives were reacted with titanocene dichloride. The reactant functionality is favorable for the formation of the poly(ester), poly(amine), poly(ether), and poly(silyl-ether) depending on the functional groups of the used siloxane precursors. The interfacial condensation technique was applied and, excepting polyesters, in the other cases, the inverse interfacial system was used. CHCl3 was used as a solvent for siloxane phase and triethyl amine was added as a hydrochloric acid acceptor. The very fast reactions occurred at room temperature with colour change from red-orange to yellow. The poly(ester) was also synthesized in solution by using DMF as a solvent. The formation of new structures was verified by FTIR and their thermal behaviour was investigated by TGA and DSC. SEM and Energy Dispersive X-Ray system (EDX) were used to show the morphology of the poly(ether). The repartition of Ti was investigated by EPR. Keywords: siloxane-titanocene copolymers; polycondensation; metallocene; siloxane
