Abstract:
In this paper, the results of measurements are presented concerning the shear
viscosities in the dependence on temperature of five hot melts adhesives based on
polyvinyl acetate – polyethylene copolymers EVAK. Using the viscosity data
measured, the accuracy of three blending models, reported in the literature for
multicomponent blends, was tested for viscosity predicting. It has been found that
no model was capable to estimate satisfactorily the adhesive melt viscosity in the
whole interval of the temperature examined. To achieve a higher accuracy of
viscosity estimation, it is necessary to incorporate into models a corrective
function of temperature.
