Patent abstract
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° 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.
