Caprolactone itself is a biodegradable polyester with a relatively low melting point (60C) but a glass transition temperature (Tg) around -60C. The high crystallinity in the polyester accounts for this property balance. It is made by metal catalyzed ring opening polymerization of epsilon caprolactone. A typical molecular weight of standard polycaprolactone homopolymer is 188k Daltons. By comparison, a 100% polylactic acid homopolymer with Mw 330k Daltons has a (Tg) temperature of +55C and a melting temperature, Tm of about 175C.
