    摘要： The invention relates to hyperbranched copolyamides (HBPAs), to their production and to their use as additives, in particular as melt viscosity modifiers in thermoplastic polymer compositions.This copolyamide is obtained by a reaction between a monomer (I): A—R—Bf with A and B=polymerization functions of a 1st and 2nd type, respectively, which are capable of reacting with each other, R=hydrocarbon-based species and f=total number of B per monomer (preferably 2≦f≦10); and a monomer (II) A′—R′—B′ or the corresponding lactams, with A′, B′ and R′ having the same definition as that given above for A, B and R, respectively. This HBPA has a I/II molar ratio such that 0.125≦I/II≦2. One of the species R or R′ of (I) or (II) is aliphatic, cycloaliphatic or arylaliphatic.For example: A=NH2 and B=COOH or A=COOH and B=NH2 with F=2.A′=NH2 and B′=COOH or A′=COOH and B′=NH2.A—R—B2, e.g.: 5-aminoisophthalic acid or 3,5-diaminobenzoic acid and A′—R′—B′=ε-caprolactam.The yarns, fibres, films and moulded parts obtained using polymer compositions (e.g. PA) to which are added HBPA according to the invention are also included in this invention.

    摘要： The invention related to the use of oligo-apiogalacturonan compounds, particularly extracted from aquatic plants of the Lemna or Zostera Genus, as an agent for stimulating the defence and resistance reactions in a plant, in particular an ornamental plant or a plant of agricultural interest, against biotic an/or abiotic stresses. The invention further relates to a method for stimulating the natural defence reactions of a plant or a portion or a plant against biotic and/or abiotic stresses that includes applying at least one oligo-apiogalacturonan compound in a liquid or solid composition on said plant or a portion of a plant or in the environment of said plant.
