“…The reluctance with which it has been used as a CF precursor is likely due to the difficulties in obtaining high molecular weight polymers without cross-linking and the lack of readily apparent commercial applications. In fact, the literature on this polymer, which has been known since 1938, has been criticized as “sketchy or incomplete in nature.” Although there have been a number of studies utilizing this polymer over the past 50 years, application of this polymer in any meaningful manner has yet to be achieved.…”

“…In fact, the literature on this polymer, which has been known since 1938, 34 has been criticized as "sketchy or incomplete in nature." 35 Although there have been a number of studies utilizing this polymer over the past 50 years, application of this polymer in any meaningful manner has yet to be achieved. This absence of commercial utility arises from the preparation and physical properties of the homopolymer.…”

Poly(Methyl Vinyl Ketone) as a Potential Carbon Fiber Precursor

Given their increasing importance in a variety of applications, the preparation of carbon fibers with well-defined chemical structures and innocuous byproducts has garnered a growing interest over the past decade. We report the preparation of medium molecular weight poly(methyl vinyl ketone) (PMVK) as a potential carbon fiber precursor material which can easily undergo carbonization via the well-known, acid-catalyzed aldol condensation with water as a sole byproduct. Rheological studies further show that PMVK (MW ∼ 50 kg/mol) exhibits excellent physical and thermal properties for the spinning of single and multifilament fibers and easily produces carbon yields of 25% at temperatures as low as 250 °C. Analysis of the carbonized product also suggests a more defect-free structure than commercially available carbon fibers.
