    • The present invention relates to branched polyamides comprising unsaturated ends comprising: at least one unit originating from a multifunctional monomer (A) having more than two functional groups, at least sequences resulting from the condensation, in the presence of at least one unsaturated monoacid, either of at least two different lactams, or of at least one lactam, at least one dicarboxylic acid and at least one diamine, or of a lactam or of an α,ω-aminocarboxylic acid, or of a diamine and of a diacid. The invention also relates to thermofusible adhesives comprising these branched polyamides comprising unsaturated ends, and to the use of these branched polyamides comprising unsaturated ends in sheathing electrical cables.
    • 本发明涉及包含不饱和末端的支链聚酰胺,其包含:至少一种源自具有多于两个官能团的多官能单体(A)的单元,至少一个由缩合产生的序列,在至少一种不饱和一元酸存在下, 的至少两种不同的内酰胺,或至少一种内酰胺,至少一种二羧酸和至少一种二胺,或内酰胺或α,ω-氨基羧酸,或二胺和二酸的至少一种。 本发明还涉及包含这些包含不饱和末端的支化聚酰胺的热熔粘合剂,以及在护套电缆中使用包含不饱和末端的这些支化聚酰胺。
