[资源] Polymerizations in Liquid and Supercritical Carbon Dioxide(good Review)

In the past few years, remarkable progress has been made in deÞning the scope and limitations of
carbon dioxide (CO2) as an inert polymerization medium. It has appear that CO2 represents a viable
solvent choice for a variety of propagation mechanisms including both chain growth and step
growth polymerizations. When the environmental advantages of CO2 are combined with its ability
to be used as a solvent/dispersing medium for a wide variety of chemical reactions, it becomes clear
that CO2 may be the solvent of the future for the polymer industry. In addition, the design and
synthesis of micelle-forming surfactants for CO2 opens the doors for use of surfactant-modiÞedCO2
as the medium for heterogeneous polymerizations. This review will focus on the use of CO2 as an
inert solvent for the synthesis and processing of polymers.
