ABSTRACT:
Blends can be obtained from polymers in particle form and powdery additives of higher melting point by heating the polymer particles so as to create a molten layer on their surface and forcing the powdery particles into said layer. After cooling, components of even very different density and morphology result inseparable. The process can be performed in a gas-loop, wherein the polymer and the additives are dragged by a hot gas flow.
