As shown from the figure, CA is affected
by acid to a much lesser extent, i.e., 2.92% & 1.84% loss in weight for CA (produced from flax fibers and cotton linters
respectively) in 30% sulfuric acid (after 4 days) compared to
29.4%, 34.3% for polystyrene and polypropylene respectively
under the same conditions. This means that the prepared CA
is more durable than polystyrene and polypropylene.
