Preferred Label : network;
Detailed label : network in polymer chemistry;
IUPAC definition : A highly ramified macromolecule in which essentially each constitutional unit is connected
to each other constitutional unit and to the macroscopic phase boundary by many permanent
paths through the macromolecule, the number of such paths increasing with the average
number of intervening bonds; the paths must on the average be co-extensive with the
macromolecule.;
Scope note : the term physical network may be used if the permanent paths through the structure
of a network are not all formed by covalent bonds but, at least in part, by physical
interactions, such that removal of the interactions leaves individual macromolecules
or a macromolecule that is not a network.; if the permanent paths through the structure of a network are all formed by covalent
bonds, the term covalent network may be used.; usually, and in all systems that exhibit rubber elasticity, the number of distinct
paths is very high, but, in most cases, some constitutional units exist which are
connected by a single path only.;
