Composition occurs as methods and results for preparing the plasticized starch-based thermoplastic composition

摘要

As for subject of this invention, (a) the step which at least selects at least one organic plasticizer for one granule starch and this starch and, (b) heat mixing this starch and this plasticizer mechanically, the step which manufactures the plasticization composition and, (the step which at least installs one which possesses the functional group which includes c) active hydrogen functionality substance optionally and, (d) in step and the option which at least install one which at least possesses two which it can react with the molecule which possesses the functional group which includes active hydrogen functional groups binder (e)Although the binder and the plasticizer and the starch and/or the reaction with the functionality substance is caused, the step which heats the blend to sufficient temperature is included, step (d) and (e) it is possible, to execute simultaneously, it is the starchy based thermoplastic composition which can be able with method, and this method of manufacturing the starchy based thermoplastic composition.
