ABSTRACT:
In order to provide a filler for degradable plastics which can simplify the stages for producing a degradable plastic, give effective plastic-degradability, and stabilize the quality of the plastic article, the filler is used as a carrier substance and effective biodegradable and/or photodegradable components are adsorbed on the surfaces of the filler particles via a surface treating agent.
