2006, Polymer Degradation and StabilityCitation Excerpt :Some unusual selectivity vs x profiles for Tol are discussed further below.) The observed steady increase with increasing x at 350 °C [37a,e] and approximately constant concentration of abstractable back-bone hydrogens do not follow if the key competition involved is transfer vs β-scission of DPP as in the usual models, i.e., kH[M]/kβ ≈ constant, but could suggest an increasing diversion of Tol from Tol to another product, specifically D. For a one-point comparison at x ≈ 0.06 where Broadbelt and coworkers [37a,e] reported <0.1 at 350 °C (large head-space), Schroder and coworkers [21b] reported 2.3 at 336 °C (closed system but small head-space); the disparity is striking. Relying more on the former data, we dare only set a target of <1 for DPP:Tol at 350 °C.
