Solvent effect in polymerization of poly(acrylate) foam
With PETA as the monomer, benzoin ethyl ether as the initiator and the energy of UV light, poly(acrylate) gelation is produced in different solvents and foams are prepared via vacuum drying technique. The polymer solvent parameter is 19.0 decided with the methods of the theoretical calculation and experiments. Solvent with phenyl and alicyclic group in molecule makes the initiator impassive, whereas solvent with ketone, alky halide, lipoid, ether and acylamide group in molecule makes the initiator active.
