La polycaprolactone (PCL) est un polyester biodégradable comportant une faible température de fusion d'environ 60 °C et une température de transition vitreuse d'environ -60 °C. La PCL est préparée par polymérisation par ouverture de cycle de l'ε-caprolactone, avec utilisation d'un catalyseur. L'utilisation principale de polycaprolactone concerne la fabrication de polyuréthanes spéciaux. La polycaprolactone confère une bonne résistance à l'eau, à l'huile, aux solvants, au chlore et au polyuréthane produit.
