    Notizen: Free radical polymerizations of methyl methacrylate and methacrylamide in DMF solution were found to be catalytically inhibited by the addition of the boron fluoride derivative of cobaloxime to the system. The nature of this inhibition is examined and equations which describe the kinetics of these catalytically inhibited polymerizations are developed. Using these equations estimates of the inhibition constants (Cz) of 7.23 × 102 and 2.27 × 102 were estimated for methacrylamide and methyl methacrylate, respectively.

    Rheokinetics of polymerization of N-laurylmethacrylate (1982)
    Stamford, Conn. [u.a.] : Wiley-Blackwell
    Polymer Engineering and Science 22 (1982), S. 402-409 
    Details
    ISSN: 0032-3888
    Schlagwort(e): Chemistry ; Chemical Engineering

    Thema: Chemie und Pharmazie , Maschinenbau , Physik
    Notizen: The free radical polymerization of n-laurylmethacrylate has been studied using a combination of rheological and kinetic methods. In addition to classical dilatometry, the extent of reaction of a polymerization was followed in a cone and plate rheometer by measuring the change in the diffraction of a laser beam shone through the polymerizing sample parallel to the plate of the rheometer. The change in diffraction was caused by the change in index of refraction of the monomer becoming polymer, which was related to the extent of reaction. Simultaneous measurements of loss and storage moduli and dynamic viscosity at 1 Hz provided the data necessary for correlating changes in the kinetics with changes in the rheology of the polymerizing system.
