Abstract : Polycondensation plastics are materials prepared on the basis of oligomers or polymers obrained by the polycondensation reaction. There are two kinds of polycondensation reactions: equilibrium -- the formation of polyesters and polyamides from dicarboxylic acids -- and nonequilibrium -- when the low-molecular reaction product cannot reverse the process, as in the formation of phenol-aldehyde and carbamide-formaldehyde polymers. Fabrication of articles from polycondensation polymers employs almost all the accustomed techniques of processing: pressing, casting under pressure, extrusion, stamping, vacuum and blow molding, and so on. The manual serves to familiarize the methods of preparing these monomers and polymers, their properties and analysis, the chemistry of polymer formation reactions, and the technology of their fabrication into article form.
