The motivation of the current work has stemmed from the fact that the selection of suitable stabilizers for nonaqueous emulsions is still challenging because of lack of general knowledge about the underlying stabilization mechanisms. The preparation and surface activity of new amphiphilic gel nanoparticles in organic solvents were investigated. A new bifunctional surfmer was prepared by reacting polyoxyethylene 4‐nonyl‐2‐propylene‐phenol nonionic reactive surfactant with maleic anhydride followed by esterification with poly(ethylene glycol). This surfmer was used as stabilizer to prepare amphiphilic crosslinked N‐isopropylacrylamide (NIPAm) and 2‐acrylamido‐2‐methylpropane sulfonic acid (AMPS) copolymer nanogel on the basis of nonaqueous radical copolymerization temperature modified method in the presence of toluene and formamide (FA) as solvents and N, N‐methylene bisacrylamide as a crosslinker. The chemical structure of the prepared nanogels was determined by Fourier transform infrared spectroscopy analyses. The morphologies of the prepared nanogels were detected by transmission electron microscopy and scanning electron microscopy techniques. The surface tension of colloidal NIPAm/AMPS dispersions was measured in FA as functions of surface age (time), temperature, and the morphology of the NIPAm/AMPS nanogels. The NIPAm/AMPS nanogels reduced the surface tension of FA from 58.2 to about 30.2 mN/m at 25°C, and a little increase in the surface tension was observed at 40°C. The prepared nanogels show great reduction in interfacial tension values between FA and styrene. The NIPAm/AMPS dispersions exhibited high surface activity and used as stabilizers to prepare crosslinked styrene‐co‐AMPS microgel in the presence of divinylbenzene and FA as organic solvents based on nonaqueous emulsion crosslinking polymerization technique.

“…5 The amphiphilic copolymer combining both hydrophilic and hydrophobic groups is one of the important branches of polymer chemicals. Because of its unique structure, a lot of research hot spots are closely related with amphiphilic polymers, such as shape memory hydrogel, 6 oil absorbents, 7,8 crude oil flow improver additives, 9 drug delivery and separation membrane. 10,11 In the leather field, the amphiphilic acrylate copolymer is a kind of multifunctional synthetic material which has the possibility to replace or partially replace traditional fatliquors.…”

With increasing demand for ecological leather, ecological fatliquors with good comprehensive properties are getting more and more attention. The amphiphilic acrylate copolymer containing both hydrophilic (carboxyl) and hydrophobic (long alkyl) groups is one of the main alternatives to conventional fatliquors. In this paper, a series of poly(acrylic acid-co-stearyl acrylate) with different relative molecular weights were prepared, and the influence of the molecular weight on their application performances were evaluated. The results show that lower relative molecular weight of copolymers is conducive to the penetration and absorption, and it improves the softness and fiber separation of leather. When the number average molecular weight (M n ) of copolymer is higher than 25,000, its penetration and absorption become worse and the resulting leather feels hard. In addition, the amphiphilic acrylate copolymers can impart excellent oxidation resistance and transference resistance to leather, which is a considerable improvement over the conventionally retanned and fatliquored leather. The copolymer has great penetration and absorption ability when M n is within the range of 9,000-15,000, and it gives leather excellent integrated properties, such as filling, softness, mechanical strength, extraction resistance, and oxidation resistance, which can meet requirements of ecological leather.

“…Recently, polymer‐based oil absorbents have attracted extensive attention for cleaning up oil spills and organic contaminants . Among polymer‐based oil absorbents, resins with self‐swelling characteristics are a new kind of oil‐absorbing material; they have many virtues, including a high oil absorbency, good absorption selectivity for water and oil, and outstanding oil‐retention performance .…”

A novel magnetic-photoresponsive oil-absorption resin (MPOAR) was synthesized via the suspension polymerization technique. Scanning electron microscopy surface morphology analysis indicated that the surface of MPOAR exhibited pore structures with different sizes. The effects of various factors in the preparation of MPOAR on the oil absorbency were studied. We found that the amount of the crosslinking agent 4 0 4-bis-(methacryloylamino)azobenzen (Azo-CL-M), porogenic agent (ethyl acetate), initiator (azobisisobutyronitrile), and modified Fe 3 O 4 had great effects on the oil absorbencies of the prepared polymer resins. The saturated absorption capacities of MPOAR for various organic solvents were determined, and we found that MPOAR could absorb 19.7 times its dry weight in CH 2 Cl 2 , 18.4 times its dry weight in CCl 4 , and 16.7 times its dry weight in CHCl 3 , respectively. In addition, the oilabsorbent beads could absorb the oils floating on water well. In particular, the saturated absorbed MPOAR could be easily collected from water by an external magnetic field. More importantly, the photoresponsive properties of the MPOAR materials could be used to accelerate the release of the absorbed oil under UV irradiation.
