Abstract
The invention relates to a process for preparing a polymer in which in situ polymerization of monomers takes place in the presence of a catalyst, in which the monomers are obtained by in situ activation of precursor monomers. According to the invention a premature polymerization is avoided, but polymerization only starts at the desired moment.
