✦ Synopsis

The rate constants for the reactions of j-carrageenan with hydrated electron and hydroxyl radical was investigated by pulse radiolysis and laser photolysis. The kinetics of the reaction of hydrated electron indicates no seeming reaction with j-carrageenan. On the other hand, hydroxyl radical reacts very rapidly with j-carrageenan at a rate constant of approximately 1.2 • 10 9 M À1 s À1 . This rate constant varies with pH.

## Abstract The hydrated electron (e^−^~aq~) and hydroxyl radical rate constants with 18 acrylate‐, methacrylate‐, crotonate‐, fumarate‐ and maleate esters are discussed. The constants approach the diffusion‐controlled limit. __k__(e^−^~aq~) and __k__(OH) change in opposite direction; if __k__(e^−^
