Synthesis, structure, and properties of new methacrylic derivatives of naphthalene‐2,3‐diol

Abstract

The synthesis of a new monomer, 2,3-(2-hydroxy-3-methacryloyloxypropoxy)naphthalene, and its copolymerization with divinylbenzene is presented. This monomer was obtained from naphthalene-2,3-diol in a two-step synthesis. Copolymers in the form of porous microspheres were prepared by a suspension-emulsion polymerization method. As pore-forming diluents, toluene, 1-decanol, benzyl alcohol, and their mixtures were used. In studies of their porous structure, two methods were used: the adsorption of nitrogen at low temperatures, which provided information about the porous structure of the material in a dry state, and inverse exclusion chromatography, which provided information about the porous structure of the polymer swollen by a good solvent. The obtained results suggest that the porous structures for the dry and swollen polymers were different.

Use of a new methacrylic monomer, 4,4′‐di(2‐hydroxy‐3‐methacryloyloxypropoxy)benzophenone, in the synthesis of porous microspheres

“…To determine the EC pore size distribution, the assumption is made that in a good solvent, chains of macromolecules form coils of a diameter corresponding to the polymer molecular weights. The diameter of the probe molecule is associated with a pore diameter that corresponds to the smallest pore allowing unhindered access for a probe of a given molecular weight 15, 16…”

“…The diameter of the probe molecule is associated with a pore diameter that corresponds to the smallest pore allowing unhindered access for a probe of a given molecular weight. 15,16 In Figure 5, cumulative and differential pore size distributions for BEP-DVB, poly(DVB), and EM-DVB are presented. On all differential curves, two maxima can be observed.…”

Synthesis, modification, and porous properties of new glycidyl methacrylate copolymers

“…Reagent grade acetone, methanol, propan‐2‐ol, chlorobenzene, chloroform, hexane, toluene, and methyl methylene 1,4‐dioxane were from POCh (Gliwice, Poland). BES.DM was obtained by the procedure described in our previous works 27, 28…”

Permanently porous copolymeric microspheres based on aromatic methacrylates

“…The new monomers described in the mentioned papers are hydroxymethacrylates synthesized from phenol and dihydroxybenzenes. Although research on the use of aliphatic methacrylate monomers in different polymerization methods to produce porous more or less crosslinked microspheres was described, only a few papers focused on the preparation of porous micro sized polymeric beads from aromatic methacrylates [21][22][23][24][25]. Copolymeric microspheres were usually prepared using DVB or methyl methacrylate as a comonomer.…”
