摘要:
Dilute solutions of linear-dendritic block copolymers of linear poly(methylmethacrylate) with hyperbranched polyphenylenegermane were investigated by light scattering methods. The obtained results were compared with characteristics of functionalized poly(methylmethacrylate) with -Ge(C6F5)(3) terminal groups, linear poly(methylmethacrylate), and hyperbranched polyphenylenegermane. The investigated samples differ by molar masses of the linear components. It was shown that molecules of functionalized poly(methylmethacrylate) in solution have a conformation that is typical for linear polymers in good solvent, while the linear-dendritic polymers in dilute chloroform solution have compact structure and high density in comparison with linear poly(methylmethacrylate).
