Abstract
The process consists in mixing, for a period tm less than the period of polymerization, in a micromixer, a flow Fm of monomer(s) to be (co)polymerized and a flow Fa of an initiator system leading to a propagation constant kp(t) greater than or equal to 500 l mol.sup.-1 s.sup.-1 and in injecting, in a polymerization reactor, a flow Fr resulting from the mixing of the flows Fm and Fa, the concentration of monomer(s) in the flow Fr being at least 10% by weight.
