For self-study, it provides a necessary feedback loop to ensure your derivation of scaling laws is correct. polymer physics rubinstein solution manual
The Rubinstein and Colby textbook is a masterpiece of scientific literature. While the search for a is a common part of the graduate school journey, remember that the goal is to develop the intuition to predict how a polymer will behave in the real world. Use solutions to guide your path, but let the physics lead your thinking. Many institutions keep reference copies of instructor guides
