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

open access: yesJournal 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 ...

Pore memory of macroporous styrene-divinylbenzene copolymers

open access: yesJournal of Applied Polymer Science, 1999
The variation of the pore structure of styrene- divinylbenzene (S-DVB) copolymer beads with the drying conditions was investigated. Macroporous S-DVB copolymer beads with various DVB contents were prepared in the presence of toluene- cyclohexanol mixtures as a diluent.

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

open access: yesJournal 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

Porous structure of highly crosslinked styrene‐divinylbenzene copolymers

open access: yesDie Angewandte Makromolekulare Chemie, 1984
AbstractPorous structure of two series of styrene (S)‐divinylbenzene (DVB) copolymers has been studied. The copolymers were prepared by suspension copolymerization of the monomers (50 wt.‐% of DVB) in the presence of heptane‐toluene mixtures as inert diluents.
