Abstract
Disposable moldings comprising a polymer (A) having a repeating structure unit in the main chain represented by the formula (I) ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 are respectively a hydrogen atom or a lower alkyl, and a polymer composition comprising the polymer (A). The moldings of the present invention disintegrate themselves due to decomposition of the polymer (A) in atmosphere, soil or water and do not cause any environmental pollution.
