Abstract

Hiodisintegrable thermoplastic resin moldings and a process for producing same are disclosed, the biodisintegrable thermoplastic resin moldings being comprised of a thermoplastic aliphatic polyester resin as a matrix resin having dispersed therein an other type of thermoplastic resin in a proportion of 40-75 weight % based on the whole resin. The biodisintegrable thermoplastic resin moldings is easily disintegrable after disposal in an environment where microorganisms exist so that the moldings can be reduced in bulkness and give no harmful effect on the life of natural plants and animals. Thus, the present invention affords an effective means for solving various problems in the treatment of disposed plastic articles.
