ABSTRACT:
Polymer compositions having enhanced biodegradability are disclosed. The compositions comprise a blend of:
(1) a polymer containing hydrolyzable bonds; and
(2) a substantially water-insoluble, pH-modifying compound capable of accelerating the hydrolysis of the hydrolyzable bonds in the polymer.
The invention also relates to polymer films comprising such compositions and absorbent articles containing such polymer compositions or films. The compositions are particularly suitable for use in disposable absorbent articles such as diapers.
