“…The sulfonated polystyrene (SPS) microspheres were synthesized according to the reported paper . SPS and the saturated solution of PrCl 3 in ethanol was mixed and stirred at room temperature for 24 h. After the products were washed by ethanol for several times, 5 wt% of urushiol dispersed in ethanol was added under stirring at 70 °C for 24 h. The unreacted urushiol oligomer was removed after washed by ethanol for several times.…”

Urushiol praseodymium‐polystyrene (UPr‐PS) Janus composite particles were synthesized by emulsion swelling assisted protruding from UPr/PS core‐shell composite microspheres. The effects of sulfonated time and the outer electronic configuration of metal on the shell of urushiol metal/PS composite microspheres, together with the effects of monomer type, monomer dosage and swelling time on the swelling behaviour, were studied. The morphology, chemical composition and thermal performance of UPr/PS core‐shell composite microspheres and UPr‐PS Janus composite particles were studied by means of scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X‐ray analyzer (EDX), Thermogravimetric analysis (TG) and infrared spectrometer (IR). Results showed that the morphology could be controlled by the metal kind, the sulfonated time, the monomer type, the monomer dosage and the swelling time. Attributing to the novel anisotropic structure, the UPr‐PS Janus composite particles will be expected to be applied in oriented catalyst. POLYM. ENG.

“…Anisotropic microparticles involving poly(4-vinyl benzyl chloride) (PVBC) were difficult to be synthesized in a large scale, and it is more challenging to regulate the shape precisely. , In fact, PVBC has a lot of potential applications as benzyl chloride is a highly active group. The chloride group can be easily substituted by nucleophilic reagent; this change will render special functionalities, such as −N(C 4 H 9 ) 3 , NaN 3 , which can be readily utilized for quaternary ammonium poly(methylstyrene-co-styrene) resin and azide-functionalized particles. , In addition, thiol-click chemistry of chloride can be applied with PVBC to provide a facile method to synthesize bioactive polymers …”

Anisotropic microparticles have plenty of applications for their asymmetric structure and precisely modified surface. In our research, the uniform anisotropic microparticles with benzyl chloride group were synthesized successfully via emulsion interfacial polymerization. By varying the degree of cross-linking and the concentration of slightly hydrophilic monomer 4-vinyl benzyl chloride (VBC), several types of microparticles with different concavities and different shapes of microparticles (hemisphere, bowl-like, egg-like, etc.) were obtained. Nanoporous microparticles with a walnut-like heterostructure were achieved with modified hydrophilic seeds with the same strategy. The potential applications of shape-controllable fluorescent microparticles and surface modification of microparticles by thiol-click reaction were explored. The modified microparticles achieved in this study are very useful in labeling, tracing, protein separation, and other biomedical fields.

“…Nowadays, many methods have been developed to fabricate Janus composite particles . Among them, the method of emulsion swelling‐assisted protrusion arouses extensive interest of researchers because the Janus particles can be produced in batch and their morphology can be controlled with this method . However, the majority of these Janus particles are composed of synthesis polymer as polystyrene (PS), poly(methyl methacrylate) or polyacrylate, etc.…”

Urushiol, the main component of the natural product of raw lacquer, can react with ester easily owing to its two adjacent phenolic hydroxyls, and urushiol-ester compounds can polymerize further attributing to its unsaturated side chain. In this work, poly(urushiol borate) (PUB) was coated on the surface of polystyrene (PS) microspheres by transesterification between urushiol and tributyl borate. Then, the core-shell composite microspheres of polystyrene@poly(urushiol borate) (PS@PUB) were obtained. Finally, we used a general method to synthesize anisotropic grenadelike Janus composite particles of PUB/PS, that is, the coreshell composite microspheres of PS@PUB were swelled assisted protrusion in the emulsion of organic monomer and water. The morphologies of PUB/PS Janus composite particles could be tuned by changing the swelling time and the dosage of organic monomer. POLYM. ENG. SCI., 00:000-000,
