Usage

General Description

Polymethacrylamide is a synthetic polymer with a wide range of commercial and industrial applications. It is a water-soluble polymer formed from the polymerization of methacrylamide monomers. This chemical is commonly used as a thickening agent in personal care products, such as hair gels and lotions, as well as in the production of various industrial and consumer adhesives. Additionally, polymethacrylamide is utilized as a flocculant in waste water treatment processes, where it helps to separate suspended particles from water through a process called coagulation-flocculation. In the medical field, this chemical is used in the production of contact lenses and as a component of various dental materials. Overall, polymethacrylamide is a versatile and widely used chemical that plays a crucial role in multiple industries and applications.

Organocatalytic Trans Semireduction of Primary and Secondary Propiolamides: Substrate Scope and Mechanistic Studies

We report a chemoselective, phosphine-catalyzed semireduction of primary and secondary propiolamides. In the presence of stoichiometric pinacolborane and catalytic n-tributylphosphine, a variety of propiolamides were successfully converted to the corresponding acrylamides in excellent yield with (E)-stereoselectivity. The reaction condition is tolerant of various functional groups including alkene, alkyne, ketone, or ester. Deuterium labeling studies established that the hydride from activated pinacolborane is added to the α-carbon and the proton on the amide nitrogen is abstracted by the ?-carbon to furnish the (E)-acrylamides. DFT calculations revealed a clear energetic driving force for the (E)- over the (Z)-isomer. (Figure presented.).

Learning from Peptides to Access Functional Precision Polymer Sequences

Functional precision polymers based on monodisperse oligo(N-substituted acrylamide)s and oligo(2-substituted-α-hydroxy acid)s have been synthesized. The discrete sequences originate from a direct translation of side-chain functionality sequences of a peptide with well-studied properties. The peptide was previously selected to solubilize the photosensitizer meta-tetra(hydroxyphenyl)chlorin. The resulting peptidomimetic formulation additives preserve the drug solubilization and release characteristics of the parent peptide. In some cases, superior properties are obtained, reaching up to 40 % higher payloads and 27-times faster initial drug release.

METHOD FOR PRODUCING N-SUBSTITUTED (METH)ACRYLAMIDE

PROBLEM TO BE SOLVED: To provide an industrial method for producing a high-purity alkoxy propionic acid amide derivative and N-substituted (meth)acrylamide in a high yield, which uses a (meth)acrylic acid as a starting material. SOLUTION: There is provided a method for producing an objective compound, N-substituted (meth)acrylamide by the step of: amidating an alkoxy propionic acid derivative, which is synthesized from a (meth)acrylic acid and alcohol and represented by the formula [1], with an amine compound; R3-NH-R4(R3 and R4 each independently represents a hydrogen atom or a linear or branched alkyl group having 1 to 6 carbon atoms or may form a saturated 5- to 7-membered ring with a nitrogen atom supporting them) in the presence of an inorganic material composed mainly of silica as a catalyst to obtain an alkoxy propionic acid amide derivative; and eliminating alcohol by the liquid phase thermal decomposition reaction of the alkoxy propionic acid amide derivative. (R1 represents H or a methyl group; and R2 represents a linear or branched alkyl group having 1 to 6 carbon atoms or an alkenyl group.) COPYRIGHT: (C)2015,JPOandINPIT
