摘要: The structure of polymer networks is closely related to the network formation (structure growth) process. A covalent a giant macromolecule dimensions commensurable with macroscopic given object. Although it can be characterized by number average structural parameters, like sol fraction or crosslinking density, its internal very different1 varying from that random loosely crosslinked vulcanized rubber dense some thermosets ceramers. Also, micronetworks (microgels) other microscopic precursors (dendritic structures, star- burst polymers, etc.) are formed first and then they grow into macronetwork same types growth processes. Vinyl-divinyl copolymerization serve as an example.2 Therefore, understanding necessary for structure, properties correlated their structure. An important role in undestanding via process played theories.
