This invention relates to a blend of biodegradable polymers comprising:
(A) about 5% to about 95% by weight of at least one flexible
biodegradable polymer (A) having a glass transition less than about
0.degree. 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.degree. 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.
