The cellulose II content was varied from 0 p.h.r to 30 p.h.r. in both cases. The influence of increasing amounts of the filler was investigated by rheometric and mechanical methods, and by wide angle X-ray scattering during uniaxial stretching. In both processes the best performance was achieved by the addition of 15 p.h.r cellulose II although different properties were found in the composites ER -
