Polyamide-polyethylene materials with compatible polyethylene phase comprises polyamide and polyethylene, where the polyethylene comprises modified and unmodified polyethylene

摘要

Polyamide (PA)-polyethylene (PE) materials (I) with compatible polyethylene phase comprises polyamide and polyethylene in the ratio of 75:25 to 99:1; where: the PE comprises modified and unmodified polyethylene in the ratio of 99:1-1:99, the PE in the polyamide matrix compatible is finely distributed, the PE is at least branched cross-linked/partially or completely crosslinked and the PA is highly branched. An independent claim is included for the preparation of (I) comprising compounding the PA with PE in melt phase under melt conditions, where the PE is added before or during the melt process, and dispersing the PE phase in the PA matrix by terminating the ionization radiation or carrying out radical crosslinking process.
