Further Consideration of Addition Polymerisation

Addition polymerisation is effected by the activation of the double bond of a vinyl monomer, thus enabling it to link up to other molecules. It has been shown that this reaction occurs in the form of a chain addition process with initiation, propagation and termination steps. [Pg.24]

Such free-radical formation may be generally indicated as [Pg.25]

The rate of formation of radicals will depend on a number of features, including the concentration of initiator, temperature and the presence of other agents. Since subsequent stages of polymer growth occur almost instantaneously it is the relative slowness of this stage which causes the overall conversion times in most polymerisations to be at least 30 minutes and sometimes much longer. [Pg.25]

The radicals formed may then react with a monomer molecule by addition, producing another radical. [Pg.25]

This radical then reacts with a further molecule of monomer, generating yet another free radical of the same order of reactivity. [Pg.25]
