摘要： A process for preparing a starch-based thermoplastic hydroxy-functional polyether comprising (1) feeding from about 40 to about 98 weight percent starch and from about 2 to about 60 weight percent of a thermoplastic hydroxy-functional polyether derived from monomers containing one or more epoxy groups into a processing equipment at a temperature and for a time sufficient to provide a compounded mixture of the components and then (2) forming the compounded mixture into pellets. The pellets are suitable for injection molding and other thermal processes.

摘要： A process for preparing a starch-based thermoplastic hydroxy-functionalized polyetheramine comprising continuously feeding from about 40 to about 98 weight percent starch and from about 2 to about 60 weight percent of a thermoplastic hydroxy-functionalized polyetheramine into a mixing screw extruder at a temperature of from about 30° C. to about 120° C. while maintaining a water content in the extruder of from about 7 to about 50 percent, continuously removing the compounded mixture from the extruder in the form of strands at a rate of from 13.5 to 2725 kg/hour, and forming the strands of compounded mixture into pellets.
