    • This invention refers to a novel process for the synthesis of polyethylene imine (PEI)-based pigment dispersants characterized by a "grafting from" approach, allowing the manufacture of solvent based dispersant systems. The polyethylene imine (PEI)-based pigment dispersant can be presented by the formula (I) X-(T) m -P-(T) n -H wherein P is a polyethyleneimine (PEI) backbone; T is a residue -CO-A-O- wherein A is C 2 -C 12 alkylene optionally substituted with C 1 -C 6 alkyl with the proviso that each linkage between P and T is an amide bond and each linkage between X and T is an ester bond, X is a modifier or terminator residue R-CO- wherein R is a linear or branched, saturated or unsaturated alkanecarboxylic acids having from 1 to 22 carbon atoms or an unsaturated fatty acid residue or a hydroxycarboxylic residue or a polyester residue obtained from polycondensation of hydroxycarboxylic acids, or an acid terminated polyether; n, m independently are a number from 1 to 100.
    • 本发明涉及一种用于合成以“接枝”方式为特征的聚乙烯亚胺(PEI)的颜料分散剂的新方法,允许制造基于溶剂的分散剂体系。 基于聚乙烯亚胺(PEI)的颜料分散剂可以通过式(I)X-(T)N - (T)N - 是聚乙烯亚胺(PEI)骨架; T是残基-CO-AO-,其中A是任选被C 1 -C 6取代的C 2 -C 12亚烷基 烷基,条件是P和T之间的每个连接是酰胺键,X和T之间的每个连接是酯键,X是修饰剂或终止子残基R-CO-,其中R是直链或支链的, 具有1至22个碳原子的饱和或不饱和链烷酸或不饱和脂肪酸残基或羟基羧酸残基或由羟基羧酸或酸封端的聚醚的缩聚获得的聚酯残基; n,m独立地为1至100的数。
