| Abstract | Polyolallylcarbonate networks were synthesized in a vacuum at room temperature, with gamma irradiation, in a quiescent radical crosslinking polymerization. The polyfunctional monomers studied here were: diallylcarbonate (DAC), monoethylene glycol bis-allylcarbonate (MEGBAC), propylene glycol bis-allylcarbonate (PGBAC), dipropylene glycol bis-allylcarbonate (DPGBAC) and tris-allylcarbonate of glycerol (TACG). The results of the sol-gel analysis of irradiated monomers and characterization by IR, elemental analysis and GPC of different extracted fractions were that polyol(allylcarbonate) undergoes crosslinking via their pi-bonds (allylic group). The gelation doses are a function of the monomer reactivities, and of the monomer's chemical composition. TACG was the most reactive, while DAC crosslinked at the highest irradiation doses. |
