The invention generally provides systems and methods for producing a chemical product. In certain embodiments, the invention provides systems that include a chemical product production unit. The chemical production unit includes a plurality of microfluidic modules configured to be fluidically coupled to each other in an arrangement that produces a chemical product from an input of a plurality of starting reagents that react with each other due to conditions within the plurality of microfluidic modules through which the starting reagents flow. The system also includes a droplet dispenser fluidically coupled to the chemical product production unit that forms and dispenses droplets of the chemical product.

A family of low-molecular-weight, main-chain thermotropic liquid-crystalline polyimides (TLC-PI) that are crosslinkable is disclosed. These all-aromatic TLC-PI are derived from (i) wholly aromatic and flexible diamine monomers, in which the linkage between the two aniline-ends contains a relatively high heat-tolerant but flexible chain constituted by two or more units of 1,4-phenoxy or 1,3-phenoxy or in combinations of both. Processes of making and using such all-aromatic TLC-PI is also provided.

A method for obtaining dimethylaminoethyl (meth)acrylate comprising reacting a (meth)acrylic ester with dimethylaminoethanol that-is at least partially renewable and non-fossil. A bio-sourced dimethylaminoethyl (meth)acrylate has a bio-sourced carbon content ranging between 45 wt % and 100 wt % relative to the total carbon weight in the bio-sourced dimethylaminoethyl (meth)acrylate. The bio-sourced carbon content can be measured according to ASTM D6866-21 Method B.

An anionic-cationic-nonionic surfactant represented by the formula (I) ##STR00001##
exhibits significantly improved interfacial activity and stability as compared with the prior art. With the present anionic-cationic-nonionic surfactant, a flooding fluid composition for tertiary oil recovery with improved oil displacement efficiency and oil washing capability as compared with the prior art could be produced.
