Molar mass determination by end group analysis amino group determination in aliphatic and partially aromatic polyamides with 1‐fluoro4ヾinitrobenzene in benzyl alcoholWASTE RUBBERRECYCLINGEnd group analysis is the most important absolute method of obtaining number-average molar mass values for polymers of...
In order to normalize the polymer property with its molar mass the intrinsic viscosity is determined by extrapolation of reduced viscosity to zero mass concentration [6]. We may now establish an activity coefficient relative to the extreme value. Assume that disintegration of the stacked asphaltene ...
Abstract: Method for producing polyacrylate adhesive compounds with a narrow molar mass distribution by radical polymerization and subsequent decolorization of colored reaction products resulting therefrom. Inventors: Prenzel, Alexander (Hamburg, DE)
The synthesis of high-molar-mass linear and 6-arm star-shaped poly(l-lactide)s (PLLA's) is presented. Dipentaerythritol and benzyl alcohol were used as initiators and Sn(Oct)2 was applied as a catalyst in the ring-opening polymerization (ROP) of l-lactide (l-LA) carried out at 130 ...
3.3. Evolution of the Course of the Reaction Since all the resulting polymers showed a broad molar mass distribution, and since their 1H and 13C NMR spectra did not differ considerably, the course of the reaction was followed with one example, namely the polymerization of benzyl chloride with ...
