Popis: | The crosslinking radical polymerization of triethylene glycol dimethacrylate in bulk in the presence of 0–40 wt % ethyl acrylate-based copolymers of various compositions is studied, and some structuralphysical properties of the crosslinked polymers are investigated. The quantitative characteristics of their porous structures, such as the specific surface areas and the total pore volumes, are measured via the low-temperature adsorption of nitrogen. During sol-gel analysis, polymer additives are removed from network polymers with the use of benzene and pores with sizes from 4 to 500 nm occupy their places. The maximum specific surface area is approximately 17 m2/g. It is found that the specific surface area and total pore volume depend on the content of the polymer additive in the initial composition. |
