New trends in polycondensation

This paper summarizes advances in the field of polycondensation attained by the scientific school of academician Korshak: heterogeneous nonequilibrium matrix polycondensation in the presence of naturally occurring and synthet ic polymeric matrices; equilibrium polycondensation in the presence of inor ganic fillers which catalyze the process and lead to formation of filled po lymers directly during the synthesis; polycondensation catalyzed by the rar e-earth metal compounds; and polycondensation of nontraditional monomers.
