Effect of reactivity of bisphenols on basic rules of low-temperature polyesterification

Bulletin of the Academy of Sciences of the USSR, Division of chemical science Aims and scope

Conclusions

  1. 1.

    A study was made of the basic rules for the low-temperature polycondensation of the acid chloride of terephthalic acid with dichlorodian and dimethyldian, i.e., with bisphenols that differ in their acidity constants.

  2. 2.

    Polyacrylates of higher molecular weight are obtained with increase in the acidity of the bisphenol, i.e., with increase in its reactivity.

  3. 3.

    When the polycondensation is run in a medium which dissolves the polymer, the dependence of the molecular weight values of the polyacrylates on the reaction temperature has the shape of a curve with two maxima.

  4. 4.

    When the polycondensation is run in a medium which does not dissolve the polymer in a wide temperature range, the value of the reduced viscosity of the polyacrylate remains constant.
