Process for preparing starch and epoxy-based thermoplastic polymer compositions |
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.
