ABSTRACT:
Provided are biodegradable polymers each of which can be obtained by introducing pyridinium groups such as N-alkylpyridinium groups or N-arylpyridinium groups into a backbone of a synthetic polymer of a vinyl compound or olefin and then quaternizing the pyridinium groups with counter anions such as chlorine ions or bromine ions. The biodegradable polymers have high compatibility with microbial cells so that articles molded or otherwise formed from the biodegradable polymers can be easily decomposed by activated sludge or under conditions buried in the ground.
