PDMS Membrane Using Phenyl as Rigid Molecular Spacer for Phenol Recovery [PDF]

Engineering in Life Sciences
Polydimethylsiloxane (PDMS) is extensively utilized for the recovery of bio‐alcohols, but it encounters significant obstacles in volatile organic compounds (VOCs) removal, because of the narrow size for molecules diffusion.

Styrene–divinylbenzene copolymers. Construction of porosity in styrene divinylbenzene matrices [PDF]

Journal of Applied Polymer Science, 1973
Experimental data are presented describing the formation of porosity in styrene-divinylbenzene copolymers as a function of the organic components present during the suspension polymerization. The reaction system contains a mixture of diluents such as toluene and hexane, which results in matrices that differ significantly in pore structure from the ...

Styrene–divinylbenzene copolymers. II. The conservation of porosity in styrene–divinylbenzene copolymer matrices and derived ion‐exchange resins [PDF]

Journal of Applied Polymer Science, 1975
AbstractThe collapse of pores in styrene–divinylbenzene copolymers and corresponding ion‐exchange resins was studied during the removal of solvating liquids. The process can be followed in a most simple way by measuring the volume of the bead‐shaped copolymers upon drying. Other parameters observed during drying were the apparent density and incidently

Effects of percent weight of divinylbenzene as crosslinking agent on the properties of eugenol–divinylbenzene copolymers

Journal of Physics: Conference Series, 2020
Abstract Synthesis of eugenol-divinylbenzene copolymers were carried out by reacting eugenol with various percent weight of divinylbenzene in a reactor at room temperature for 24 hours in the presence of sulfuric acid as a catalyst. Methanol was used to quench the copolymerization process.
