説明
The increase in the degree of polymerization with conversion has been investigated by measuring the degree of polymerization, the rate of polymerization and the k′ of Huggins. The polymerization was carried out in bulk and butyl acetate solution system. At the about fifteen per cent conversion, the rate of polymerization increases rapidely, but the increase in the degree of polymerization becomes gradual. These results can be explained from the fact that the gel effect becomes conspicuous at about fifteen per cent, and therefore the polymer radicals grows until they are terminated by the chain transfer of monomer. In the bulk polymerization, the degree of polymerization represented in the follow equation: P=760W0.074 where P is the degree of polymerization and W is conversion (%). The k′ of Huggins did not show remarkable change from the initial stage to final stage, and therefore it is not proper to think that the increase in the degree of polymerization is due to the effect of the branching of polymer.
