ABSTRACT:
The invention relates to a process for preparing a composition contains a polymer and a crosslinking agent which comprises mixing a polymer that is solid at room temperature with a crosslinking agent, the polymer and the crosslinker having complementary reactive groups, at a temperature at which the viscosity of the polymer (measured according to Emila) is less than 5000 dpas, in a means for achieving a homogeneous composition in such a short time that less than 20% of the reactive groups of one of either the polymer or crosslinking agent has reacted, and subsequently cooling and comminuting the composition.
The mixing is preferably effected in a static mixer at a temperature higher than 140.degree. C.
