Link nodes

Figure 32. (a) A simple 6-connected 3D net (4V) formed by linking nodes with trigonal prismatic geometry. A single net in [Eu Ag(CN)2 3(H20)3] has this topology, (b) Three nets of the type shown in (a) that interpenetrate in [Eu Ag(CN)2 3(H20>3]. Circles represent Eu. Linear connections represent EuNCAgCNEu links (shown in full in the central net). 

Several performance characteristics of rubber such as abrasion resistance, pendulum rebound, Mooney viscosity, modulus, Taber die swell, and rheological properties can be modeled by Eq 7.34. " A complex mathematical model, called links-nodes-blobs was also developed and experimentally tested to express the properties of a filled rubber network system. Blobs are the filler aggregates, nodes are crosslinks and links are interconnecting chains. The model not only allows for... 

Figure 3.34 shows the PROGRES transformation for the example forward rule for a connection of Fig. 3.28 b). The left-hand side consists of the half link ( 2) and the respective dominant increment ( 1), as all other increments of this rule are context increments. In general, all non-context increments and their connecting edges are part of the left-hand side. The link node is further constrained by a condition that requires the attribute status of the link to have the value unchecked. This ensures that the transformation is only applied to half links that have not already been checked for possible rule applications. 

A correct analysis of the crystal structures is fundamental in order to avoid misinterpretations, that can easily occur, about the network topology and, when present, the type and extent of the entanglement of distinct motifs. The rationalization of these, often complicated, structures implies a sequence of steps leading to the basic nets of linked nodes. 

Other explanations and mechanisms for this occurrence have also been advanced determination by TMA of the average number of freedom of polymer segments between cross-linking nodes of PF resin hardened networks indicate that additive accelerated PF... 

Model polymer networks are perfea cross-linked polymers, comprising linear polymer chains of highly homogeneous molecular weights, interconnecting cross-linking nodes from which a constant number of chains emanate. 

Quasi-model polymer networks are polymer networks with an almost perfect stmcture, with the most frequendy occurring imperfection concerning the constancy in the number of chains emanating from the cross-linking nodes.
