This approach allowed maintenance of muscular attachments to the femur, soft tissue closure and resulted in a residual limb of acceptable length with a broad weight-bearing surface that was fitted with a prosthesis successfully.
A third broad weight loss at temperatures above 300 °C is likely associated with the evolution of remaining residue of citric acid and also dehydroxylation of alumina.
The threshold pressure for precipitation of various monodisperse molecular weights was investigated, and the effectiveness of this technique to fractionate a polymer with a broad molecular weight distribution was evaluated.
By regulating the hydrolysis time (10 180 min), a broad molecular weight range of SF was obtained (263.1 82.7 kDa) Gel point increased with a decrease of SF molecular weight.
The SMPs presented a broad molecular weight distribution from smaller than 1 kDa to over 100 kDa.
Without a well-defined active site, rational catalyst design and characterisation is difficult, and the polymer produced by such a system has a broad molecular weight distribution.
All four ethoxy groups were active in the initiation process, but a broad molecular weight distribution was found and a low percentage (presumably <1 mol%) of cyclic oligomers was formed.
On the other hand, III which has a broad molecular weight distribution has been synthesized by AROP of 1,3,5,7-tetramethyl-1,3,5,7-tetravinylcyclotetrasiloxane(V) catalyzed by phosphazene P4-t-Bu superbase.
Therefore, a broad molecular weight range as prepared here by transition metal initiators is hardly accessible by the amine-initiated NCA polymerization.
