Endocellulase attack

The first section will deal with the preparation of the HEC solutions, the determination of the refractive index increment, and the exact Mw determination by light scattering before and after endocellulase attack, using a simultaneous zero-angle and zero-concentration extrapolation of the reduced scattering values. 

Figure 3. Computer plot obtained by isochronous interpolation of the experimental light-scattering data (O) of HEC during endocellulase attack. The Langrangian interpolation functions are given by the horizontal curves ana the isochronous interpolated Kc/Re values by A. The quadratic least squares extrapolations to zero angle ( ) are given by the...

Figure 7. Parallelism between (0) Mw, (A) Mz, and ( ) Mn values, obtained from the distribution analysis of the gel fractionation of HEC before and during endocellulase attack. The experimental Mn values are given by the abscissa and they are repeated in the ordinate to show the parallelism between the different average molecular weights.
