Random flight behavior

Theta Solvents Give Random-flight Behavior... 

The central chains treated by Baumgartner are relatively long. Redner [55] did computer simulation experiments to investigate the behavior of shorter central chains, but his random flight chain was as short as iV = 15. 

Since global polymer behavior is not affected by local details of the polymer chain, its formulation may be made by use of a suitably coarse-grained polymer chain. We may choose the random flight chain, the spring-bead chain, the Edwards continuous chain, and others, depending on the global property concerned, the method of formulation, and the accuracy of the results to be derived. In what follows, we are concerned with the theories developed with the Edwards continuous chain.
