Summary

Description
English: Schematic views:
  • left, linear chains of macromolecules (case of a thermoplastic polymer);
  • right, a three-dimensional macromolecule (case of a thermosetting polymer). The tri- and tetravalent cross-linking nodes are represented in black. Such a network is insoluble and does not melt.
Dimension of a circle (monomer unit): approximately one ångström (Å).
Français : Représentation schématique :
  • à gauche, des chaînes de macromolécules linéaires (non réticulées) (cas d'un polymère thermoplastique) ;
  • à droite, d'une macromolécule tridimensionnelle (cas d'un polymère thermodurcissable). Les nœuds (tri- et tétravalents) de réticulation sont représentés en noir. Un tel réseau est insoluble et infusible.
Dimension d'un cercle (unité monomère) : environ un ångström (Å).
