Petroleum-based polyesters polycaprolactone

Indeed, a large number of biodegradable polyesters are based on petrolenm resources, obtained chemically from synthetic monomers and polycaprolactone, poly-esteramide, or aliphatic/aromatic copolyesters can be distinguished. Generally, these petroleum-based polyesters are soft at room temperature since their glass transition temperatures are lower. [Pg.65]

The majority of petroleum-based compostable plastics belong to the polyester family, including Ecoflex , polycaprolactone (PCL), Ecovio , poly-butyrate adipate terephthalate (PBAT), and aliphatic copolyesters (The Impacts of Degradable Plastic Bags in Australia 2003). Table 4.14 lists several commercially available biodegradable or compostable plastic products. [Pg.92]
