multicomponent biodegradable polymeric materials based on polysaccharides type unmodified starch.

摘要

Compatibilized blends of a polyester BIODEGRADABLE HYDROPHOBIC, MODIFIED STARCH OR OTHER SIMILAR NO polysaccharide containing less than 1% water by weight, other biodegradable polymers that may be hydrophobic, plasticizer, and other additives. MIXTURES ARE PRODUCED IN WATER ABSENCE. The polyester polymer is poly PREFERRED ({EP} caprolactone) AND CORN STARCH PREFERRED PROCEDE OF. A SMALL AMOUNT OF AN AGENT OF STRETCH UNICO is incorporated to deliver high elongation at break, ESPECIALLY IN compositions containing a surface active SIGNIFICANT AMOUNT OF STARCH. Starch is a phase discontinuous MAY BE PARTIALLY OR PLASTIC AND COMPLETE polymer polyester is the continuous phase. Polymers preferred have surface active properties and are water resistant MOISTURE.
