| titleOfInvention | Multi-acid and multi-base graft copolymeric dispersants |
| abstract | A dispersant for use at the interface between an organic medium and a particulate solid, said dispersant comprising a surfactant reaction product of a polyether functionalized polyacid that reacts with an amino polybasic species and its salts, wherein said polyether functionalized polyacid species comprises a polyacid portion of 10 to 500 repeating units, said polyacid portion comprising at least two free acid groups selected from the types consisting of a carboxylic acid, salt of a carboxylic acid, anhydride of a dicarboxylic acid, phosphorous acid and acid of sulfur, and said repeating units being obtained from free radical polymerization monomers that had contained a polymerizable carbon-carbon double bond, wherein said polyether-functionalized polyacid comprises two or more polyether segments with an oxygen or amine group (J) near one end of the polyether and connected to said portion p olyacid through ester, amide and / or imide bonds, wherein said two or more polyether segments comprise a Q 'type polyether segment having the formula -J- (Cδ H2aδ-O) T- (CH2CH2O) X -R2 where δ is 3 and / or 4, -J- is -O-, -N (H) -, or> N-, T has 4 to 45 repeating C3 and C4 alkylene oxide units in total and X consists of up to 45 repeating ethylene oxide units per segment, and R2 is a hydrocarbyl group with up to 36 carbon atoms, and / or a G 'type polyether segment having the formula -J- (CδH2δ-O) L - (CH2CH2O) M-R1, where δ is 3 and / or 4, -J- is -O-, -N (H) -, or> N-, M consists of 3 to 60 ethylene oxide units and L consists of up to 20 C3 and C4 alkylene oxide units in total per segment, and R1 is a hydrocarbyl group with up to 36 carbon atoms, in one embodiment M must be greater than L, and in one embodiment, the ratio M: L after rounding up to two places beyond the decimal it is at least 1.50: 1 or more desirably at least 2.00: 1 and in u An embodiment T + X must be equal to or greater than 8 and the ratio of X: T after rounding up to two places beyond the decimal, is less than 1.50: 1 and more desirably less than 1.40: 1; wherein the numerical ratio of said acidic groups of said polyacid with respect to the carbonyl groups in the form of an ester, amide or imide type functionalized with G 'type polyether segments with respect to the carbonyl in the form of an ester, amide or imide type functionalized with Q 'type polyether segments is 20-90: 0-35: 5-80 where the quantity of Q' is further defined as the sum of the variables Qa '+ Qb' where Qa 'is the portion of Q where J is -N (H) - or> N- and Qb 'is the portion of Q' where J is -O-; with the conditions that a) the sum of G '+ Qa' must amount to at least 2.5, more desirably 5, and b) Qa '+ Qb' + G 'must amount to at least 10; wherein said amine polybasic species comprises a polyamine that can be linear or branched having a molecular weight of 140 to 100,000 g / mol; wherein said reaction product includes two or more ionic and / or covalent bonds between said polyether functionalized polyacid and said amine polybasic species and the weight ratio of the polyether functionalized polyacid to the amine polybasic species is 1: 1 to 35: 1, more desirably 1: 1 to 30: 1, and preferably 2: 1 to 30: 1. |
