Discarded conventional plastics remain in the environment for decades. They block sewers and drains, disfigure the streets, beaches and countryside, and kill wildlife on land, in rivers and oceans. To overcome these problems increasing attention has been paid to the development of degradable plastics (1) starch-based, biodegradable, (2) aliphatic polyesters, biodegradable, (3) photodegradable, and (4) oxo-biodegradable. [Pg.150]

Why are many aliphatic polyesters biodegradable and which parameters control the differences in the degradation rate ... [Pg.304]

As already explained, the intermediates of polyester biodegradation are the monomers and oligomers obtained by the cleavage of ester bonds. Therefore, these are the substances to be considered for environmental fate and ecotoxicity investigation. [Pg.69]

Stable miniemulsions in water, consisting of PDL droplets (prepared by using a nonionic surfactant and ultrasonication), could be polymerized by lipase PS to yield high-molecular-mass polyester biodegradable nanoparticles [63]. [Pg.295]
