Abstract:
The problem of the synthesis and study of the properties of thermoreactive oligomers and polymers containing reactive acetylenic groups, leading to the formation of compounds with a three-dimensional structure, are examined. Pathways leading to the formation of oligomers and polymers from acetylenic monomers during their polycyclotrimerisation with retention of the residual acetylenic groups as well as the methods of synthesis of various oligomers and polymers with subsequent introduction of acetylenic groups into the latter are indicated. The possible structural transformations of the acetylenic groups during the hardening process with formation of rigid and cross-linked polymers without the evolution of volatile products are discussed. The bibliography includes 127 references.
