Abstract: Copolymer comprising (i) 40-73 mole% a basic structural unit which is produced by reacting an olefinic double bond-containing monomer, and (ii) 27-60 mole% a substituted dicarboxylic acid derivative structural unit (I)-(XIV), is new. The basic structural unit does not comprise species of dicarboxylic acid derivative structural unit. The molar proportion of (I)-(VI) is 5-100%, and (II)-(VI), (VIII), (IX), (XI) and (XII) is 5-100%. The molar proportion of the groups Q1 or Q2 is 10-100% based on the groups E1, E2, Q1 and Q2. Copolymer comprising (i) 40-73 mole% a basic structural unit which is produced by reacting an olefinic double bond-containing monomer, and (ii) 27-60 mole% a substituted dicarboxylic acid derivative structural unit of formula (C(=O)(X1-R1)-C(Z1)(Z2)-C(Z3)(Z4)-C(=O)-X2-R2) (I), (C(=O)(X1-E1)-C(Z1)(Z2)-C(Z3)(Z4)-C(=O)-X2-E2) (II), (C(=O)(X1-Q1)-C(Z1)(Z2)-C(Z3)(Z4)-C(=O)-X2-Q2) (III), (C(=O)(X1-R1)-C(Z1)(Z2)-C(Z3)(Z4)-C(=O)-X2-E1) (IV), (C(=O)(X1-R1)-C(Z1)(Z2)-C(Z3)(Z4)-C(=O)-X2-Q1) (V), (C(=O)(X1-Q1)-C(Z1)(Z2)-C(Z3)(Z4)-C(=O)-X2-E1) (VI), (C(=O)(O-H)-C(Z1)(Z2)-C(Z3)(Z4)-C(=O)-O-R1) (VII), (C(=O)(O-H)-C(Z1)(Z2)-C(Z3)(Z4)-C(=O)-O-E1) (VIII), (C(=O)(O-H)-C(Z1)(Z2)-C(Z3)(Z4)-C(=O)-O-Q1) (IX), (X)-(XIII) or (C(=O)(O-H)-C(Z1)(Z2)-C(Z3)(Z4)-C(=O)-O-H) (XIV), is new. The basic structural unit does not comprise species of dicarboxylic acid derivative structural unit. The molar proportion of (I)-(VI) is 5-100%, and (II)-(VI), (VIII), (IX), (XI) and (XII) is 5-100%. The molar proportion of the groups Q1 or Q2 is 10-100% based on the groups E1, E2, Q1 and Q2. Z1-Z4 : H, linear 1-4C alkyl and/or polymer main chain linking sites, where two polymer main chain linking sites are present per each (I); X1, X2 : NH and/or O; R1, R2 : optionally branched and optionally saturated at least 4C organic group (containing at least 3 O and does not comprise amine- and ammonium groups); E1, E2 : N,N-disubstituted amino group of formula (-Y1-N(R11)-R12) (Ia); either R11, R12 : 1-24C alkyl or 7-18C arylalkyl (both optionally substituted and optionally branched) or 4-10C cycloalkyl or 6-18C aryl (both optionally substituted); or R11+R12+N to which R11 and R12 are bonded : aliphatic or aromatic and optionally substituted 3-10C cyclic group; Y1 : optionally substituted and optionally branched 1-24C alkylene and/or optionally substituted 6-18C arylene; Q1, Q2 : quaternary ammonium group of formula ((-Y1-N +>(R11)(R12)-R13)(M ->)) (Ib); R13 : 1-24C alkyl or 7-18C aralkyl (both optionally substituted and optionally branched) or 4-10C cycloalkyl or 6-18C aryl (both optionally substituted) and/or H; and M : anion. Independent claims are also included for: (1) preparing the copolymer; (2) a dispersion comprising a dispersing medium, dispersed particulate solid which is present in the form of an inorganic filler, an inorganic or organic pigment, carbon nanotubes and/or graphene, and 0.1-10 wt.%, preferably 0.3-4.5 wt.% the above copolymer as a wetting- and dispersing agent; and (3) a particle formulation comprising 30-99.9 wt.% particulate solid, and 0.1-70 wt.% the above copolymer.
