The present disclosure provides polyamine-fatty acid derived lipidoids (e.g., compounds of Formula (I) or (II)) and methods of preparing the lipidoids. A described lipidoid includes R—C(═O)—O— moieties (where R is a lipid moiety), which may be hydrolyzed into non-toxic fatty acids. Also provided are compositions including a described lipidoid and an agent (e.g., polynucleotide, small molecule, peptide, or protein). The present disclosure also provides methods, kits, and uses that involve the lipidoids or compositions for delivering an agent to a subject, tissue, or cell and/or for treating and/or preventing a range of diseases, such as genetic diseases, proliferative diseases, hematological diseases, neurological diseases, immunological diseases, gastrointestinal diseases, respiratory diseases, painful conditions, psychiatric disorders, and metabolic disorders. ##STR00001##

Provided herein are compounds, such as compounds of Formula (I), and pharmaceutically acceptable salts, hydrates, solvates, polymorphs, co-crystals, tautomers, stereoisomers, and isotopically labeled derivatives thereof, and compositions, methods, uses, and kits thereof. The compounds provided herein are lipids useful for delivery of polynucleotides, such as mRNA, for the treatment and/or prevention of various diseases and conditions (e.g., genetic disease, proliferative disease, hematological disease, neurological disease, liver disease, spleen disease, lung disease, painful condition, psychiatric disorder, musculoskeletal disease, a metabolic disorder, inflammatory disease, or autoimmune disease).

The present disclosure relates to a polymerizable surfactant with reducibility and a preparation method thereof. The acid anhydride is reacted with a long-chain fatty alcohol to obtain an intermediate of an anhydride monoester, and then the obtained intermediate is reacted with the hydrochloride of dimethylaminohalogenated alkane, and a polymerizable surfactant with reducibility is obtained by post-processing. The polymerizable surfactant can not only play a role as a reactive emulsifier and copolymerize with monomers to obtain a soap-free emulsion, but also form a redox initiation system with peroxide, and conduct redox emulsion polymerization at room temperature. The soap-free emulsion synthesized by the polymerizable surfactant synthesized can greatly reduce the energy consumption in production, and can carry out one-step emulsion polymerization at normal temperature or low temperature to obtain an environment-friendly emulsion with a branched structure, thereby obtaining coatings with excellent water resistance, weather resistance, and impact resistance.

Fatty amine compositions made from a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives are disclosed. In another aspect, fatty amidoamines made by reacting a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives with an aminoalkyl-substituted tertiary amine are disclosed. The fatty amines or amidoamines are advantageously sulfonated, sulfitated, oxidized, or reduced. In other aspects, the ester derivative is a modified triglyceride made by self-metathesis of a natural oil or an unsaturated triglyceride made by cross-metathesis of a natural oil with an olefin.

The invention relates to the production of (meth)acrylic esters according to a continuous process by transesterification, and in particular to the purification of a crude reaction mixture comprising a C.sub.4-C.sub.12 (meth)acrylic ester using a divided wall column employed in a particular configuration. This configuration results in a simplification of the purification process with a reduced energy consumption and a minimized content of impurities present in the purified (meth)acrylic ester. The invention also relates to a process for the production of C.sub.4-C.sub.12 (meth)acrylic ester comprising this recovery/purification process.
