Preparation of poly(ethylcyanoacrylate) nanofibers by vapor phase polymerization using alcohol initiators

N Marinov, M Simeonova
Anionic initiators, containing either hydroxyl or thiohydroxyl group as initiating moieties, were used for preparation of poly(ethylcynoacrylate) (PECA) nanofibers by vapor phase polymerization. The hydroxyl (alcohol) and thoalcohol groups as nucleophilic entities are capable to attack the double bond of monomer resulting in polymerization in vapor phase and formation of nanofibers at high relative humidity atmosphere. Different techniques such as scanning electron microscopy, thermogravimetric

The results obtained show differences in the properties of PECA nanofibers formed via vapor phase polymerization more probably due to the different nucleophilicity of both initiating species.
