Abstract
The present invention relates to linear or branched polyamides obtainable by polymn. of a mixt. contg. a bifunctional monomer of type AB and/or a monomer mixt. of type ΛΛ+ΒΒ in the presence of: a) one or more mols., having one or more carboxyl and/or amino functional groups, selected from carboxylic acids or an ester or an anhydride thereof, and/or amines and/or polyhedral oligosilsequioxanes (POSS);; and b) one or more phosphorus contg. mols., reactive with only one reactive group during polymn., contg. at least a -POOH group and/or a salt thereof; and c) one or more metal hydroxides and/or metal salts, wherein the metal belongs to groups from 1 to 14 of the Periodic Table; provided that when the phosphorus contg. mols., as defined under b), contain the -POOH groups in salified form with a metal as defined under c), then the presence of the metal hydroxides and/or metal salts, as defined under c) is optional.Pubblicazioni consigliate
