AI Technical Summary

Problems solved by technology

Problems that occur with currently available pigment compositions include: (i) the composition separates or settles into its components over time, which may require periodic remixing or agitation, and (ii) undesired changes in rheological properties
The problem with this type of system is that, after dispensing is complete, there is inevitably residual colorant left in or on the nozzle which dries over time and partially or completely clogs the nozzle, making the Subsequent precise allocation becomes impossible
This is an even more problem with open nozzle tinting machines, which have nozzles that have no spigots or valve systems to isolate the colorant from the atmosphere once the addition is complete.

Embodiment 1

[0519] The mixture of 72 g of intermediate A1 and 5G intermediate B1 was stirred at 80 ° C for 30 minutes. The resulting product was a viscous liquid having an acid value of 70 mg kOH / g and an amine value of 84 mg kOH / g.

Embodiment 2-47

[0521] Example 2-47 is prepared in a manner similar to that of Example 1, and the type of the type and the type of the polyamine in the acid compound is different from the following table.

Abstract

The present invention relates to novel polymer compositions which are obtained by neutralizing a polymer P having at least one functional moiety of the formula (I) bound to at least one of the termini and / or to the backbone of the polymer, with an oligomeric or polymeric amine PA having at least 2 amino groups per oligomer or polymer molecule.

Description

[0001] The present invention relates to a novel polymer composition, which is obtained by neutralizing at least 2 amino groups with each oligomer or polymer molecule and polymer P, which has at least one as follows. The functional structural portion of the formula (I) defined by the article, the functional structure portion binds to at least one end and / or main chain of the polymer. [0002] The invention also relates to a method of preparing a polymer composition as defined herein, a liquid composition comprising a polymer composition as defined herein and a polymer composition as a dispersant as defined herein as a dispersing agent. . [0003] Inventory background [0004] The pigment is an organic or inorganic dry powder that combines a mixture of primary particles, aggregates, and agglomerates. For industrial and consumer coating compositions, both solvent type or water-based, pigments should be uniformly dispersed in the entire coating composition to ensure uniform appearance...
