✦ Synopsis

Ab~racl--Kinetic effects of excluded volume and selective adsorption in macromolecule solutions have been studied for an arbitrary position of reacting groups along the chain. It has been shown that the reactivities of similar functional groups can depend upon their location along the chain and also upon the nature of the solvent.
