Abstract
The invention provides liquid injectable copolymers of TMC and HTMC that are degradable in vivo. Degradation can be tailored by adjusting the amount of HTMC in the copolymer, the initial molecular weight of the copolymer, and the characteristics of the initiator used in its preparation. Specifically, the degradation rate increases as the amount of HTMC incorporated into the copolymer increases, as the molecular weight of the copolymer decreases, and as the hydrophobicity of the initiator decreases. Moreover, the degradation yields products such as glycerol and carbon dioxide that are non-toxic in vivo, and which will not cause a substantive change in tissue pH upon implantation in vivo. The copolymers may be used in applications such as drug delivery and as coatings.
