The kinks between two linear chain units with a single planar ring in each have been found to be the point of an almost free rotation around these units because of the ring symmetry and the possibility of rotation. The polymer chain flexibility is, as a result, the function of only the ...
The flexibility of poly(2,4,5-trichlorophenyl methacrylate) (p1463-1475)Light scattering in benzene and intrinsic viscosities [] in tetrahydrofuran,chloroform,1,4-dioxane,and benzene of poly(2,4,5-trichlorophenyl methacrylate) (PTCPh)... N Hadjichristidis - 《Macromolecular Chemistry & Physics》...
Our long record in polymer science gives us expert knowledge in manufacturing advanced polymer safety barriers and developing workplace safety innovation.
The flexibility of macromolecules leads to independent motion of separate molecular segments in polymer solutions, which is reflected in such properties as the sharp increase in the number of particles of the solute relative to the solvent’s true content. Thus, polymer solutions are characterized by...
f, The flexibility of silica and PC/PMMA fiber was measured by a dynamic mechanical analyzer at physiologic frequencies. For c–f, n = 3 fibers, the bold line indicates the mean, and the shaded regions indicate s.d. g, A conventional silica fiber pierces an agarose (1.5%) membrane...
The ever-growing demand of portable and wearable electric devices requires energy storage devices with flexibility and wearable compatibility while not sacrificing the performance too much. This requires the electrode and electrolyte materials becoming robust and durable under mechanical deformations, which gr...
its glass transition temperature up to ~41%. Therefore, the combined use of FR elements such as silicon and nitrogen and the flexibility of sol-gel routes can facilitate the synthesis of hybrid structures containing well dispersed inorganic phases, which could replace halogen-based flame retardants....
On the basis of these criteria it then describes the preparation of a set of polymer blends using PLA and a hydrocarbon rubber (PI). This combination of two mechanistically distinct polymerisations formed a novel copolymer in which the incorporation of PI significantly increased flexibility. 第三种...
between polymer chains (like adding water to mud to make it easy in molding) 1. To increase flexibility, elongation and to reduce hardness and stiffness. 2. To lower the processing temperature (energy saving, decomposition preventing) Plasticizers Plasticizer properties: • Low viscosit...
1). This novel structural motif locks SLPL and SLPH together, providing a structural basis for the stability of the H/L complex15. Fig. 2: Interactions and flexibility in C. difficile SLPH/SLPL (H/L) complex. a Paperclip organisation of the interacting domains LID/HID is maintained by...
