US Patent 7572856 Process for preparing a flame retardant polyamide compound

The invention relates to a process for preparing a flame retardant polyamide compound comprising melt-mixing of a composition comprising at least a polyamide polymer having a weight-average molecular weight of at least 10.000 g/mol, an amount of 1-100 wt. % relative to the total weight of polyamide of a flame retardant, and an amount of 0.1-30 wt. %, relative to the total weight of polyamide, of a polyamide oligomer having a weight-average molecular weight of at most 7.500 g/mol.
