Linear and three-dimensional polymers

The second method of characterizing the chemical order of a reaction is by the concentration of reactive groups, [R]. This method is most applicable to reactive oligomers that polymerize into both linear and three-dimensional polymers. Let the initial concentration be [R]o and the final one be [R]oo. Then the chemical degree of conversion Pch is... 

In Figs. 136 and 136 are illustrated diagrammatioally the manner in which certain linear and three-dimensional polymers are built up. These diagrams have of course nothing to say concerning the spatial relationships of the various chains with...
