Regulating systems (balances) with variable radius of gyration are allowed provided they comply with criteria One (A) and One (B).
Using the rotational isomeric state theory, the mean square radius of gyration and its temperature coefficient for the polymer chain with large side groups are derived.
The obtained characteristic ratio of mean-square radius of gyration and its temperature coefficients for the long Poly(dimethylsilylene)chains with side groups approach the asymptotic value of 2.
