Abstract
Several samples of cellulose acetate polymers with varying degrees of substitution (DS) between 0.7 and 1.7 have been prepared and tested fo r their biodegradation potential. The original and biodegraded polymer s were characterized using chemical techniques as well as nuclear magn etic resonance, Fourier transform infra-red spectroscopy, gel permeati on chromatography, solution viscosity and X-ray diffraction. DS, solub ility and crystallinity have been investigated as possible factors aff ecting biodegradability. (C) 1997 Elsevier Science Ltd.
