Limiting viscosity number and molecular weight measurements on poly(1,2-cyclohexene oxide)☆

Limiting viscosity number and molecular weight data are reported for fractions of poly(1,2-cyclohexene oxide) in benzene and toluene. The following relationship was found at 35°C |ƞ|=3·5X105M0·83ƞ for 20 000 < Mƞ < 500 000 Molecular dimensions in solutions were determined by using the Kurata-Stockmayer-Roig and Stockmayer-Fixman treatments. The characteristic ratio 20M was found to be 0·35 × 10−10 and 0·39 × 10−16 cm2 by the two methods respectively. The conformational parameter σ of the polymer has been compared with the values calculated for other linear polyethers.
