Abstract
In order to establish a kinetics of the reaction between reactive groups attached to polymer side chains, we have measured the reaction rate of photodimerization of anthryl groups attached in part to polymethylmethacrylate (PMMA) side chains in dilute solutions. A dynamic light scattering (DLS) measurement and a gel permeation chromatography (GPC) have been used to estimate the volume of an individual polymer coil. At the initial stage of the reaction, the volume does not change so greatly and the reaction obeys a second order kinetics in the same manner as a monomer-like model compound. When the reaction proceeds up to some extent, the volume decreases rapidly and the reaction is restricted to deviate from the second order kinetics
