โœฆ Synopsis


Acrolein was grafted onto polyethylene f i l m with radiation energy in order to make functional polymers containing hydrazone, oxhe, and oxyacid. The kinetic analysis of the grafting reaction revealed that the irradiation dose affected not only the initiation but also the propagation and termination steps. The activation energies were 12.5 kcal/mol for propagation and 23.3 kcal/mol for termination, respectively. All the introduced aldehyde groups, free, hydrolyzed, and used for ring formation, participated in the reaction with phenylhydrazine. The conversions of aldehyde group to hydrazone, oxhe, and oxyacid were small when the grafting yield of acrolein was high.
