Biodegradable polycaprolactone-containing

Polycaprolactones (see also Section 25.11), although available since 1969, have only recently been marketed for biodegradable purposes. Applications include degradable film, tree planting containers and slow-release matrices for pharmaceuticals, pesticides, herbieides and fertilisers. Its rate of biodegradability is said to be less than that of the polylactides.

Z class materials are defined by Novamont as biodegradable and compostable (Fig. 6.18). They contain compatibilized aliphatic polyesters and particularly polycaprolactone at concentrations up to 50% as the main synthetic components. The products are mainly used for films and sheets. The mechanical properties are reported in Table 6.4. Their sensitivity to humidity is greatly improved in comparison with A grades. Their compostability was... 

Poly(lactide-co-Z-caprolactone) is a derivative of polycaprolactone, which is a biodegradable polyester used in the synthesis of polyurethane polymers. Drachman et al. placed stents containing the polymer poly(lactide-co-Z-caprolactone) into pig vascular beds to study the effects of the stent on neointimal regrowth. They reported that the paclitaxel releasing stent was able to curtail vascular intimal regrowth and in-stent restenosis at all the time points they tested from 7 to 180 days [2]. However, in studies conducted in other animals it became apparent that arteries did not heal completely following stent-mediated release of paclitaxel [3],...
