Highly ramified structure in which essentially each constitutional unit
connected to each other constitutional unit
and to the macroscopic phase boundary
by many paths through the structure, the number of such paths increasing with the
number of intervening constitutional units; the paths must on average be co-extensive
with the structure.
- 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 that are connected
by a single path only.
- Modified from previous definition. The definition proposed here is a
generalization to cover both polymeric networks and networks comprised of particles.
