the production of materials. “Macrocycles as monomersÏ
(Brunelle) is based on the advantage of ring-opening polymerisation that no volatile or other by-product is generated
during the reaction. Since equilibrium favours the linear form,
high yields can be obtained.
Two chapters discuss novel techniques of polymerisation.
“Synthesis with ultrasoundÏ (Price) shows how, apart from the
time-honoured study of degradation, high-intensity ultrasound Ðnds useful application in synthesis. It can lead to the
production of polymers without the use of an added initiator
or emulsiÐer, particularly important for biomedical or food
applications. “Plasma polymerisationÏ (Yasuda) describes the
deposition of polymer as an ultrathin layer (e.g. on glass,
metal or ceramic) or as a modiÐed surface layer on a plastic
material.
The remaining contributions focus on particular types of
polymers. “Heterocyclic polymersÏ (Sillion & Rabilloud)
describes two types of fully cyclised heterocyclic aromatic
polymers : high-molecular-weight soluble linear species and
short thermosetting oligomers, end-capped with thermally
reactive groups. “Dendritic macromoleculesÏ (Hawker &
Frechet) demonstrates that both convergent and divergent
approaches have made great strides, producing molecules with
a high degree of control. Terminal groups, building blocks
and core units can all be manipulated to produce the desired
range of structures.

This is the second volume in a series of great value to those
concerned with the synthesis of polymers. Following the
pattern of its predecessor of four years ago, it comprises eight
self-contained reviews of recent developments in polymer synthesis, prepared by experts in the Ðeld concerned. There is no
link between the chapters other than their intrinsic common
aim. It thus remains to comment on the individual contributions.
Four chapters deal with a particular type of polymerisation
mechanism : radical, cationic, metathesis and macrocycleopening. “Radical polymerisationÏ (Davis & Haddleton) covers
living and pseudo-living radical polymerisation involving iniferters or nitroso compounds (e.g. TEMPO), but was written
just a little too early to include MatyjaszewskiÏs versatile
copper-bipyridyl system. It also considers catalysed chain
transfer based on cobalt macrocycles. “Living cationic polymerisationÏ (Sawamoto & Kamigaito) describes systems free
from transfer and termination, mainly associated with the
HI/ZnI initiating combination. It is possible to produce
2
uniform (monodisperse) polymers, end- or side-group-functionalised polymers, and block or star polymers, as well as
macromonomers. “MetathesisÏ (Feast & Khosravi) is a continuation of a chapter in the Ðrst volume, and concentrates on
the combination of ROMP with other mechanisms and with
