This invention relates to a blend of biodegradable polymers comprising: (A) about 5% to about 95% by weight of at least one flexible biodegradable polym er (A) having a glass transition less than about 0~C, (B) about 5% to about 95% by weight of at least one rigid biodegradable polymer (B) having a glass transition greater than about 10 ~C, and (C) about 0.25 to about 10 weight% of at least one compatibilizer (C), said percentages being based on the total weight of the polymer blend; where the polymer blend has a higher zero shear melt viscosity than polymers (A) and (B) separately. |
