Modified polyamides, compositions based on same and macromolecular compounds used to obtain them

摘要

The invention concerns polyamides modified by a multifunctional compound. Finished articles formed from said polyamides or from compositions based on said polyamides exhibit excellent mechanical properties, and a very good surface appearance. The modified polyamide is obtained by mixing in melted form a polyamide and a polyamide macromolecular compound comprising star-shaped or H-shaped macromolecular chains.
