Materials L-lactide(LLA)[Aldrich, 99+%], stannous 2-ethyl hexanoate,Sn(Oct)2, catalyst[Sigma, 95%] and the purifying solvents were utilized according to the reported commercial purity. Dihydroxy-terminated PCL ranging in molecular weight from oligomeric compounds[530 and 2000(2K) Daltons] to polymeric species[43,000(43K) and 80,000(80K) Daltons] were obtained from Aldrich and Union Carbide, respectively. 

In this chapter, the term oligomeric compound refers to products prepared by repeatedly linking one or several types of monomer to a growing chain of monomers. Included are biopolymers, such as peptides or oligonucleotides, and non-natural products, such as peptide nucleic acids, peptoids, or other synthetic polyamides.
