The invention comprises biodegradable terephthalate polymers comprising the recurring monomeric units shown in formula (I), wherein R is a divalent organic moiety; R' is hydrogen, an aliphatic, aromatic or heterocyclic residue; x is ≥ 1; and n is 3-7,500, where the biodegradable polymer is sufficiently pure to be biocompatible and is capable of forming biocompatible residues upon biodegradation. Medical and drug delivery devices comprising the polymers and a biologically active substance, articles useful for implantation or injection into the body, fabricated using the polymers, and methods for controlled release of biologically active substances using the polymers, are also described. |
