摘要:The present disclosure relates to the field of synthesis of block copolymers, and polymeric nanofibers having a core-shell morphology produced therefrom. The present disclosure relates to the field of synthesis of block copolymers where one block is more hydrophobic than the other block and is a different composition. The disclosure also relates to uses of these polymeric nanofibers in various applications, such as reinforcing a polymeric matrix and for coatings applications.

摘要:The present disclosure relates to a process for making a branched copolymer comprising reacting polymer monomers with macro-azo polyethylene glycol (PEG) initiators and cross-linkers, in the presence of a chain transfer agent, wherein said process comprises the step of traditional radical polymerization. The process further comprises a step of dialysis to obtain polymer nano-particles. The process further comprises the step of loading the polymer nanoparticles with a hydrophobic compound. The present disclosure also relates to the use of the polymer nanoparticles for the slow release of a hydrophobic compound in a neutral or alkaline environment or the fast release of a hydrophobic compound in an acidic environment.

摘要:The present invention relates to monomers of formula (I) having a nitrogen atom that can be protonated at relatively low pH values (e.g., less than pH 9.5 or less than pH 9), polymers containing monomeric units derived from these monomers, anion exchange separation articles having the polymers grafted to a porous substrate, and methods of using the anion separation articles to separate mixtures of materials with different ionic content are described. Advantageously, the anion exchange separation articles can be used to separate biomaterials that cannot be subjected to high pH conditions (e.g., greater than 9 or 9.5) and/or to high ionic strength conditions (e.g., greater than 0.5M or 1M).

标题 :Synthesis of Degradable Polymers Downhole for Oilfield Applications
发明人：KHLESTKIN VADIM KAMIL EVICH
权利人:KHLESTKIN VADIM KAMIL EVICH
摘要:A method is given for polymerizing monomers downhole to create well treatment polymers. The monomers each contain two polymerizable groups and a degradable group or groups which allow the polymer to degrade under downhole conditions, for example by hydrolysis. Polymerization downhole allows easier, more precise, placement of polymer. Polymer obtained from monomers pumped downhole may be used, for example, for fluid diversion plugs, isolation plugs, formation consolidation, flowback control, and fluid loss control. Synthesized polymer may form gels, films, solids or other structure in treated wellbores, fractures, and/or formations. After the desired effect is achieved, the deposited polymer degrades and the polymer degradation products dissolve, leaving the wellbore, fracture and/or formation clean, with no damage that might have decreased fluid flow.

摘要:Methods for preparing free radical or visible light curable (VLC) acid-containing polymers in an aqueous solution are provided. In one embodiment, the method comprises reacting polymers having reactive carboxylic acid groups with a methacrylated oxazoline or oxazine, collectively referred to hereafter as “methacrylated unsaturated cyclic imino ethers,â€? in an aqueous solution at a temperature of from about 50° C. to about 75° C. In another embodiment, the method comprises an additional step of preparing the carboxylic acid-containing polymer in an aqueous solution and then reacting the carboxylic acid-containing polymer with the methacrylated cyclic imino ether in the aqueous solution. The present invention also relates to free radical or VLC acid-containing polymers, and dental restoratives that comprise such polymers. Methods of attaching an oxazoline or oxazine to a carboxylate group on a polymer in an aqueous solution are also provided.
