摘要：

This invention relates to blends of high, optionally medium, and low molecular weight polyesters where at least the low molecular weight polyester is substituted with an acidic moiety, the biodegradation of the blends being controllable by selection of the mean molecular weigh of each fraction, the quantity of each fraction in the blend and the amount and pKa of the acidic moiety(ies).
