Abstract
Core - sheath fibers of polyvinyl alcohol/polyethylene composites are synthesized by ethylene polymerization with titanium tetrachloride incorporated PVA nanofiber (NF) as catalyst precursor in presence of methyl aluminoxane (MAO) as a cocatalyst. The process also involves the initial preparation of PVA nanofiber by electrospinning followed by its reaction with titanium tetrachloride. The obtained titanium incorporated PVA was found to be insoluble in protonic solvent due to the reaction of OH group in PVA with titanium tetrachloride leading to the formation of a cross-linked mat. Thermal analysis of core-sheath fiber composite indicated the presence of polyethylene due to observation of melting peak at 134 °C. PVA-PE fiber composite is characterized by FTIR, SEM, and contact angle data. The results demonstrate that the presented approach is useful for synthesizing incompatible classes of polymer composite fibers such as polyvinyl alcohol/polyethylene with core-sheath morphology.
