NEW METHOD FOR SUSTAINABLE POLYMER COMPOSITES PROCESSING

Polymer blends and composites have been obtained in a newly designed multifunctional mixing twin screw extruder. It is assembled as a module that allows for obtaining of two independent polymer streams with separate control. This unit can fulfill as well: Longer mixing process so that during polymer melt passing the chemical reactions can be performed more successfully and completely; Effective pressure and temperature control in the conditional 'reactive zone' that is a part of the extruder barrel; Good homogenizing action, distributive and dispersive mixing. Because of the precise construction the best friction ratio can be obtained that in turn ensures as well the best possible intermeshing in the polymer melt. The application of newly developed design can turn the processing machine into speedy technological stirred reactor triggering some innovative processes as stable and successful green chemical methods.
