Reactive hydroxylated and carboxylated polymers for use as adhesion promoters

A polymer complex is disclosed which is the reaction product of one or more polymers having a terminal or pendant hydroxyl group, or a terminal or pendent carboxyl group, or combinations thereof, with at least one metal complex and one alkyl phosphate. This polymer complex acts as an adhesion promotion agent as well as a viscosity stabilizer when formulated in a printing ink or coating.

METHOD FOR CLEAVING COORDINATE BOND OF COMPLEX POLYMER
20230323072 · 2023-10-12 · ·

A method for cleaving a coordinate bond of a complex polymer that contains at least one polymer chain and a plurality of nitrogen- and/or phosphorus-containing functional groups which are bonded to the polymer chain and capable of forming coordinate bonds, wherein the coordinately-bondable nitrogen- and/or phosphorus-containing functional groups form a coordinate bond via a metal ion, characterized in that the method includes dissolving the complex polymer in a solvent containing a free ligand, to cleave the coordinate bond.

PHOSPHORAMIDITE SYNTHESIS ON-DEMAND

A process for synthesizing phosphoramidites by immobilizing a phosphitylating agent on an activated resin to create a loaded resin and then bringing the loaded resin into contact with a suitable substrate. The phosphoramidites are synthesized within minutes from applying the starting materials. Thus, the process makes it possible to create specific phosphoramidites on-demand as they are needed in further applications. The substrates to be applied are mostly nucleosides, thus to create nucleoside phosphoramidites for subsequent oligonucleotide synthesis.

FUNCTIONALIZED (METH)ACRYLIC POLYMER OR COPOLYMER MACROPARTICULATES AND METHODS FOR PRODUCTION AND USE THEREOF

Macroparticulates may be formed through at least partial self-assembly by reacting an epoxide-containing (meth)acrylic polymer or copolymer with a compound bearing a nitrogen nucleophile, such as iminodiacetic acid or ethylenediamine. When the epoxide-containing (meth)acrylic polymer or copolymer is formed into a predetermined shape before reaction with the compound bearing the nitrogen nucleophile, a profile of the predetermined shape may be at least partially maintained and undergo expansion in the course of forming the reaction product, thereby producing macroparticulates having a larger volume than the predetermined shape itself. An internal cavity may be formed when generating the macroparticulates in this manner. Optionally, a hexasubstituted benzene or a supramolecular receptor may be adhered to a surface portion of the macroparticulates, either covalently or non-covalently. The compound bearing a nitrogen nucleophile may be further modified to form one or more functionalities capable of binding an analyte.

CONTAMINANT REMEDIATION WITH FUNCTIONALIZED (METH)ACRYLIC POLYMER OR COPOLYMER MACROPARTICULATES AND SYSTEMS RELATED THERETO

Macroparticulates may be formed through at least partial self-assembly by reacting an epoxide-containing (meth)acrylic polymer or copolymer with a compound bearing a nitrogen nucleophile. An internal cavity may be formed when functionalizing the (meth)acrylic polymer or copolymer in the presence of a hindered amine base. When appropriately functionalized, the macroparticulates may be used to sequester a contaminant from a substance in need of contaminant remediation, such as produced water or flowback water from a wellbore job site. Reclaimed water obtained from the macroparticulates may be utilized to form a treatment fluid. The macroparticulates may be located within a continuous flow line, particularly within a removable cartridge, to promote removal of at least one contaminant from a substance in need of contaminant remediation. The substance in need of contaminant remediation and/or the macroparticulates may be visually or spectroscopically interrogated to determine whether the macroparticulates have become saturated with contaminant.
