ABSTRACT:
Disclosed is a hydrodisintegratable material which, when injection molded into an object, acquires and maintains the desired shape without becoming brittle. Additionally, in the presence of water, the molded object has the ability to rapidly disintegrate and disperse when subjected to standardized agitation testing. The moldable material typically includes: (1) from about 7.5 to about 85 weight percent of at least one water dispersible polymer; (2) from about 7.5 to about 85 weight percent of at least one xerogellant; and (3) at least one volatile material, where the weight percentage of all volatile materials present in the material is within a range which is defined, at its lower end, by the weight percentage of all volatile materials which assures that the material will not become brittle upon being molded and is defined, at its upper end, by the highest weight percentage of all volatile materials which results in the material satisfactorily conforming to the desired physical configuration upon being molded. A process for forming such an object is disclosed.
