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 ...

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 ...
