ABSTRACT:
A thermoplastic basic polymers in pourable form are mixed with similarly pourable carrier polymers dispersable or soluble in the basic polymers with a cross-linking agent to produce cross-linked polymer moldings. These mutually compatible components are heated under further mixing to a reaction temperature above the melting range of the basic polymer and processed. The reaction of free radicals leads to bonds between polymer chains and/or the degradation of polymer chains.
Porous carrier polymers which contain at least one organic peroxide and/or coagent incorporated in the fine pore structure as a fluid silane-free cross-linking agent are mixed in the basic polymer. Peroxide-containing carrier polymers are heated, coagent-containing carrier polymers are irradiated.
The moldings are used for example for cable and sheath isolation, pipes for hot water lines and highly stressed injection moldings.
