In the case of ring opening or addition polymerization, the end group can be
predetermined via initiator choice or by end capping such as shown in Scheme 4
-5 for polycaprolactone and for polystyrene. The reactions in Scheme 4-5 are
merely ...

The newly formed alkoxide end groups are capable of initiating the
polymerization of additionally introduced ethylene oxide monomer, but this
reaction is slower than that of the first step. Polymerization times of a day or more
at 75°C were ...

This technique involved the interaction of poly(diphenylsiloxane) and poly(
dimethylsiloxane) via condensation of their disilanol end groups in the presence
of stannous octoate. Obviously, this approach will give products of ill-defined
structure.
