The free radical copolymerization and formation tendency of a charge transfer complex between acrylonitrile and N-vinyl phthalimidine was conducted in dimethyl formamide using benzoyl peroxide as an initiator.
Copolymer formed was found to be consisted of the two monomer units in 1:l mole ratio.
Moreover, copolymerizati on rate was the maximum when the feed composition was 1:l in mole ratio.
The experimental conditions were [AN]_(0)=O.5×10^(-2)mole/liter, [NVPH]_(0)=0.73mole/liter∼3.75mol/liter and λ=340 and 345 nm, it was found that the equilibrium constant of the charge transfer complex calculated by using the Benessi-Hildebrand technique was 0.197 liter/mole.
This fact is closely related to form a charge transfer complex these two monomers. Activation energy of the copolymerization was found to be 4.2Kcal/mole.
Thermal and solubility behaviers of the copolymer were also examined.
