<p><P>PROBLEM TO BE SOLVED: To provide a biodegradable resin composition containing dextrin and polylactic acid, and having improved biodegradability and versatility while keeping high mechanical strength of the polylactic acid. <P>SOLUTION: The biodegradable resin composition in which a dextrin continuous phase and a polylactic acid continuous phase are in such a co-continuous phase that both phases are mixed and fused to each other, is produced by: blending polylactic acid and a plasticizer for the polylactic acid to form a plasticized polylactic acid composition beforehand; blending dextrin and a plasticizer for dextrin to form a plasticized dextrin composition beforehand; then kneading the plasticized polylactic acid composition and the plasticized dextrin composition. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
