NMR Studies of Solid Polymers,ons and conformations of polymer molecules, to polymerization chemistry, and to the structures of important classes of molecules both natural and synthetic. These powerful studies employ polymer solutions and depend on high resolution methods of NMR. In the real systems where polymers are used, howe储备 发表于 2025-3-27 07:17:45

Some Aspects of Dielectric Relaxation of Amorphous Polymers Including the Effects of a Hydrostatic udies have been made using applied pressure as an additional variable . The general feature that emerges is that many amorphous polymers exhibit two relaxation regions, α and β, at low temperatures which appear to coalesce at higher temperatures forming what we shall term the (α β) process [Armada 发表于 2025-3-27 17:11:49
