“…A 67:33 (v/v) solution of porogenic solvent to monomer mixture was mixed and sonicated for about 8 min. For the column containing lauryl acrylate, the solubility limitations of adding more than 10% lauryl acrylate as reported by other groups , were overcome by sonicating the polymerization mixture while heating gently until solution turned from cloudy to clear. It was not possible to increase the lauryl acrylate component further with this porogen due to its low solubility regardless of additional sonication or heating.…”

The development of organic porous polymer monoliths represents an alternative approach to stationary phase design. The use of these materials has helped to rekindle interest in capillary electrochromatography. Although a large number of investigations have explored different monolith recipes, polymerization conditions, and application challenges, few investigations have addressed the fundamentals of this separation mode with this type of material. This study addresses the thermodynamics of the reversed phase retention mechanism on 100% butyl acrylate and 1:3 butyl:lauryl acrylate (volume/volume ratio) porous polymer monoliths used in a capillary electrochromatography mode. Linear van't Hoff plots yield enthalpies of retention of −3.9 to −14.3 kJ/mol on two different, but related columns for five selected hydrophobic analytes across a thirty degree temperature range. Minimum plate heights were only moderately impacted over this temperature range.

“…Some researchers have reported a lot of fibrous materials which can be used as oil absorbents, for example, the fibers prepared via dry-wet spinning (Feng and Xiao 2006), gelation spinning (Xu and Xiao 2010), wet spinning (Zhao et al 2011), melt spinning (Zhao et al 2012), reactive extrusion-melt spinning (Ma et al 2013), and graft modification (Li and Wei 2012). Due to good practicability and wide applicability, non-woven fabrics, such as melt blown polypropylene non-woven fabric (Zhao et al 2013a, b), are another important fibrous material which can be used as oil absorbent (Radetic et al 2008).…”

Electrospun polystyrene materials have been employed as oil absorbents, but they have visible drawbacks such as poor strength at low temperature and unreliable integrity because of brittleness and insufficient cohesive force among fibers. Butyl acrylate can polymerize into flexible chains, and its polymer can be used as elastomer and adhesive material. Thereby it is possible to obtain the material that has better performance in comparison with electrospun polystyrene material through the electrospinning of the copolymer of styrene and butyl acrylate. In this work, a polymer was synthesized through suspension polymerization by using styrene and butyl acrylate as comonomers. The synthesis of the copolymer of styrene and butyl acrylate was verified through dissolution and hydrolysis experimental data; as well through nuclear magnetic resonance spectrometry. The viscous flow activation energy of the solution consisting of copolymer and N, N-dimethylformamide was determined via viscosity method and then adopted to establish the entanglement characteristics of butyl acrylate’s chain segments. Finally, in order to electrospin the copolymer solution into fibrous membrane, the effects of monomer feed ratio and spinning parameters were investigated. The prepared fibrous membrane was found to have a potential use as oil absorbent.

“…The unsaturated lauryl methacrylate bond can polymerize and cross-link given the proper conditions. 36,37 The lauryl methacrylate long nonpolar side chain plays an important role in this study. 33 ,38 In the twin-screw extruder it is subjected to a shearing force while in a high-temperature and high-pressure environment, which makes the lauryl acrylate easy to cross-link and polymerize.…”

In this paper, biocomposite films were prepared by using recycled low density polyethylene from marine plastic waste and wheat straw micropowders from common agricultural wastes in northern China. In order to determine the optimal ratio, eight experimental groups were set up for comparative testing. For further improving the performance of the biocomposite film, the three-dimensional network skeleton construction and targeted repairing technology of the material were designed. The specimens were characterized by a HD camera, a universal examination machine, a research grade inverted microscope, and a thermogravimetric analyzer. The results indicate that the agglomeration of powders reduces the tensile strength of the material, and the elongation at break depends on the properties of the polyolefin matrix itself. The reinforced biocomposite film has a 13.7 MPa tensile strength and a 243% elongation at break. It has slightly better mechanical properties than ordinary materials, which can be used as an economical, thermally stable, and environmentally friendly material to manufacture new packaging and courier bags.
