2010年12月1日 · Using DVB, three new porous copolymers in the form of microspheres were prepared, characterized and used as adsorbents for phenol and its chlorinated derivatives. As the monomers: 4,4′-bis (maleimidodiphenyl)methane (BM), 2,3-bis (2-hydroxy-3-methylacryloyloxy-propoxy)naphthalene (2,3-NAF) and 2,3-epoxypropyl methacrylate (GLY) were used.

The series of highly crosslinked, hydrophilic stable spherical microspheres based on the new aromatic tetrafunctional methacrylate monomers and divinylbenzene (DVB) were prepared by...

2021年4月20日 · The thermal properties of pure polymer-silane hybrids and the materials loaded with organic adsorbates were investigated using TG, DTG and DSC techniques. In Figure 9, the TG, DTG and DSC curves measured for the synthesized DVB-TEVS materials are presented. One can state that they show similar thermal behaviour with several stages of the ...

2007年5月21日 · Differential scanning calorimeter (DSC; Perkin–Elmer DSC-7, UK) was used to observe the glass transition temperature of the poly(GMA) and poly(GMA-co-DVB) particles. The samples were heated up to 250 °C at a heating rate of 20 °C/min under a nitrogen atmosphere and quench cooled at a maximum cooling rate, and then reheated in a second time.

Styrene-based resins used for the preparation of ion exchange resins and polymer supports are also obtained by oil-in-water (O/W) method of styrene (St) and divinylbenzene (DVB) (and a functional monomer) [29, 30].

2013年3月26日 · Divinylbenzene (DVB), Merck (Darmstadt, Germany), and 1-vinyl-2-pyrrolidone (VP), Fluka (Buchs, Switerland), were washed with 5 % aqueous sodium hydroxide in order to remove inhibitors. Poly (vinyl alcohol) and α,α′-azoisobisbutyronitrile from Fluka (Buchs, Switerland) were used without purification.

2011年5月1日 · The series of highly crosslinked, hydrophilic stable spherical microspheres based on the new aromatic tetrafunctional methacrylate monomers and divinylbenzene (DVB) were prepared by...

2003年1月1日 · The interaction and thermal behavior of the poly(4-vinylpyridine-co-divinylbenzene)–Cu(II) complex were studied using infrared (IR), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA).

2019年12月6日 · Divinylbenzene (DVB) is used as a cross-linker in the synthesis of copolymers due to its good mechanical properties and susceptibility to chemical modification [16]. The main strategy of the present work is the preparation of SAC latex particle with negative surface charged and its reaction with DVB.

2010年12月8日 · In this article, characterization and thermal properties of highly crosslinked, hydrophilic stable spherical microspheres based on the new aromatic tetrafunctional methacrylate monomers and divinylbenzene (DVB) prepared by emulsion–suspension polymerization in the presence of pore-forming diluents (toluene/decan-1-ol) were presented.
