ABSTRACT We report on the application of biodegradable cyclic poly (L-lactide)(PLLA) as new stabilizer; synthesis and application of a cyclic PLLA-clay hybrid material as recyclable catalyst support. Cyclic PLLAs were used to stabilize palladium nanoparticles synthesized by a wet chemical method. It was found that the palladium particles were smaller with cyclic PLLA stabilizer (∼ 5–10 nm) than the particles obtained from linear PLLA. The cyclic ...
