Control of transesterification in polyester blends 330 $aThe ability of condensation polymers to undergo additional chemical reactions, so-called transreactions, is really fascinating. These processes lead to novel copolymers with desired composition and sequential order, allow to enhance the compatibility and to minimize molecular weight fluctuations during polycondensation and processing and to provide for chemical healing of laminates of condensation polymers.An international team of highly reputated polymer chemists and physicists discusses here, first of all, various types of transreactions, but additional condensations are also detailed in 606 $aPolymerization 606 $aCopolymers 606 $aPolymers 615 0$aPolymerization. 615 0$aCopolymers. 615 0$aPolymers. 676 $a547.28 676 $a547.7 676 $a668.9 702 $aFakirov$b Stoyko 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910830328303321 996 $aTransreactions in condensation polymers$94076382 997 $aUNINA
